Crocheting rectangles is the next step after learning how to crochet a basic square. It is relative easy to follow up with and serves as the building block for an array of projects, from cozy blankets to charming amigurumi and stylish accessories. They offer a different shape compared to squares and can create interesting design possibilities when combined with other shapes or motifs in larger crochet pieces.

What is a crochet rectangle? 

A crochet rectangle is a four-sided shape with four right angles, where opposite sides are equal in length. As opposed to a square, the four sides are not equal in length, but two opposite ones are the same length and likewise for the remaining two.  

It's formed by working rows of stitches that increase and decrease in a specific pattern to create longer sides and shorter ends, resulting in a rectangular shape. 

How to crochet a rectangle step by step? 

Crocheting a rectangle is very similar to crocheting a square, just that the sides are uneven. This time I start off with a chain of 7 instead but the total number of rows are similar to the square pattern, before moving onto the rounds.  

Row 1: Chain 7 

Row 2: Sc6, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 - 4st 

If you simply end off at Row 5, you will get a basic rectangle shape that is the easiest to crochet up. In the next part, I ended off with an additional step to crochet around the basic piece above just to tidy it up and make a neater rectangle, still using single crochet stitches.   

How to start a crochet rectangle? 

With the pattern written above, here are the steps described in words for how to start, continue and finish off a crochet rectangle. First, we start off with a slip knot, then chain a certain number of stitches inside the foundation chain to create the length of the rectangle. Then we work into the first row, across the foundation chain. With the example above, we worked single crochet stitches into the foundation chain.  

How to continue crocheting a rectangle? 

After completing the foundation chain and the first row, we have the turning chain, in the above case, since we are using single crochet stitches, simply chain 2 and turn your work. This chain serves as the turning chain to begin the next row.  

As for subsequent rows, repeat the same stitch pattern across each row and continue repeating the rows until the rectangle reaches the desired height. In the above pattern example, it was just 5 rows. 

How to finish up the crochet rectangle? 

To finish up the crochet rectangle, complete the intended number of rows, which forms the height of the rectangle and then fasten off your yarn, leaving a tail for weaving in the ends. Use a yarn needle to weave in any loose ends to secure them.  

This basic pattern can be modified by changing the stitch pattern, increasing or decreasing the size, or incorporating different colours to create variations in the rectangle. Adjust the length and height based on your project's requirements or preferences. 

How do you make a rectangle in crochet? 

In addition to the short pattern mentioned above, I have continued on below to crochet around all four sides of the rectangle to make the final piece neater and more even. So firstly, follow all the steps mentioned above and then continue on below in the answer for the next section.  

How to crochet rectangle in rows?  

The simple short rectangular crochet pattern is repeated here: 

Row 1: Chain 7 

Row 2: Sc6, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 - 4st 

Turn and rotate whole piece, sc1 in last st, then place stitch marker here. Continue in rounds now, instead of rows.  

Round 1: Sc1 in last st (as mentioned above), sc2 along side, 2sc1 in corner, turn and rotate, sc4 along bottom, 2sc1 in corner, turn and rotate, sc3 along side, turn and rotate, sc6 - 20st  

The final completed rectangle should have 20 st in the round, with the edges in all sides tidied up nicely. I have used this method before to create capes for my amigurumi. 

How to crochet a rectangle in the round? 

Crocheting a rectangle in a round is slightly different from crocheting in rows as in the example above. Unlike crocheting square which involves crocheting around a magic ring, for crocheting rectangles in a round, we will be starting with a foundation chain. When first starting out this pattern, it might look more like an oval rather than a rectangle. As you do multiple increases in the corners, then the rectangle becomes more obvious. See the pattern example below: 

Row 1: Ch6  

Row 2: Sc4, 3sc1, go around and crochet on the other side of chain, sc3, 2sc1 – 12st  

Row 3: 3sc1, sc3, 3sc1, sc1, 3sc1, sc3, 3sc1, sc1 – 20st 

Row 4: Sc1, 3sc1, sc5, 3sc1, sc3, 3sc1, sc5, 3sc1, sc2 – 28st  

Row 5: Sc2, 3sc1, sc7, 3sc1, sc5, 3sc1, sc7, 3sc1, sc3 – 36st 

Just for easier reference, note that the corners of the rectangle are always formed in the middle of the 3sc1, for each subsequent round.  

How to crochet a rectangle granny square? 

This is included for completeness because there are rectangle granny squares! Since this is not my area of passion, I am not the best equipped to give step by step instructions so here I am linking out to a tutorial with pictures and videos to help teach you how to achieve a rectangle granny square. You can check it out here. 

Can you make a rectangle with c2c crochet? 

Yes, you can create a rectangle using the Corner-to-Corner (C2C) crochet technique. While C2C is often used to create squares or square-shaped patterns, you can modify the technique to create rectangular shapes by adjusting the increases and decreases. Experimenting with different stitch counts and row lengths will help you achieve the desired size and proportions for your rectangular C2C project. The process involved in C2C crochet involves multiple steps, which would be better explained in detail with the post below.  

How to single crochet a rectangle?  

For this next section, we will be talking about using different types of stitch heights to crochet a rectangle. We have explored how to single crochet a rectangle in rows above and also briefly how to do so in a round. For the next 2 parts, we will be talking about crocheting a double crochet rectangle in both rows and rounds.  

How do you double crochet a rectangle? 

This pattern is the same as crocheting a single crochet rectangle in rows as mentioned above but this time, the stitches are replaced with double crochet stitches and you will have to add in taller turning chains correspondingly. See more of the pattern below: 

Row 1: Chain 7 

Row 2: (Sc1 into 2nd ch from hook, ch3), dc6, ch3 and turn – 6st 

Row 3: Dc6, ch3 and turn - 6st 

Row 4-5: Repeat Row 2 - 6st 

How to do double crochet rectangle in the round? 

This is slightly more complex than crocheting single crochet rectangle in the round. It follows the single crochet pattern above in a round closely except that the corners are thicker with 5 double crochet stitches in the same stitch (as opposed to just 3 single crochet stitches in the corners). Also, the turning chains need to be added as well.  

Row 1: Ch6 

Row 2: (Sc1 into 2nd ch from hook, ch3), dc4, 5dc1, go around, dc3, 4dc1, sl st to top of ch3 – 16st 

Row 3: (Ch3, 5dc1), dc5, 5dc1, dc1, 5dc1, dc5, 5dc1, dc1, sl st to top of ch3 – 27st 

Likewise, the corners always formed in middle of 5dc1, similar to how the corners are formed in the middle of the 3sc1 above.  

How to crochet different sizes of rectangle? 

To crochet different sizes of rectangles, there are a few ways to go about doing it as I will elaborate on below. Simply, you could either increase the length of the initial foundation chain or increase the number of rows or rounds you work into. Doing this while all maintaining the same proportion will get you different sizes of rectangles. Of course, an even easier way is to use thicker weight yarn and a larger crochet hook to work up a bigger rectangle faster, or even consider using taller stitches like double and treble crochet stitches to make larger rectangles! I will go through some short pattern examples below.  

How do you make a smaller rectangle crochet pattern? 

For a small rectangle, you could follow the easiest example I stated above which is a 7x5 rectangle or the pattern below:   

Row 1: Chain 7 

Row 2: Sc6, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

This is technically using the shortest stitch, the single crochet stitch (apart from slip stitch) and a rectangle of 7x5 is as small as it gets, although you could try to make the rectangle even smaller. Shorter foundation chains do not make for uniform perfect rectangles so I did not make the pattern any shorter or smaller. 

How to crochet a long rectangle? 

There are 2 ways you can crochet a long rectangle, either by starting off with a longer foundation chain and then the number of rows are fewer or you should start with a short foundation chain and include many subsequent rows after that. I have included 2 short pattern examples below to illustrate what I mean.  

Row 1: Chain 10 

Row 2: Sc4, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

In this case, the initial chain is the longer side of the rectangle while the rows are the shorter side. Here is the other example: 

Row 1: Chain 6 

Row 2: Sc5, ch1 and turn - 4st 

Row 3-10: Repeat Row 2 – 4st 

This is the other example where the initial foundation chain is the shorter side, while the number of rows crocheted corresponds to the longer side.  

While on the other hand, if you choose to crochet with taller stitches like double crochet stitches, then technically the height of the row will double that of single crochet stitches, so to achieve the same long rectangle, you could finish it in a shorter time period! I mentioned more under double crochet rectangle examples above.  

Why is my crochet rectangle slanted? 

A slanted crochet rectangle often occurs due to a few reasons, like inconsistent tension might cause one side of rectangle to be tighter or looser than the other, causing the slanting. This can also happen to the turning chains at the end of rows, causing the edges to be slanted. Sometimes, it might be uneven stitch counts within rows like missing or adding stitches.  

Why is my crochet rectangle curving? 

Another common issue apart from slanting is curving of the crochet rectangle. This can also similarly happen with tension variation especially for beginners, which can cause the corners of the rectangle to curl. Apart from maintaining consistent tension and maintaining the right stitch count, sometimes using a hook that is too small for the yarn weight might cause a denser fabric and the curling issue might arise. Finally, incorrect increases or decreases within the pattern or inadequare or excessive shaping can also contribute to curving.  

Why does my crochet rectangle get smaller? 

If you see your crochet rectangle getting smaller, you could be miscounting your stitches like missing or skipping stitches, or perhaps the tension is too tight, and it is turning out smaller than expected. Apart from skipped stitches, accidental decreases within the pattern will definitely make the rectangle smaller than intended. Also do make sure you are using the right crochet hook size for the yarn weight, as smaller hooks tend to make the stitches tighter and the rectangle eventually gets smaller.  

How to keep my crochet rectangle edges straight? 

A few simple ways to keep your crochet rectangle edges straight would include keeping your tension consistent throughout each row of the rectangle. Make sure you count your stitches regularly especially after completing each row, paying attention to the turning chains as well. Double check that you are following the pattern accurately, in particular when they mention increases and decreases in the row. These simple steps should help keep the rectangle edges straight and even. 

What can I make with a rectangle crochet? 

Rectangles in crochet are versatile and can be used to create various projects. Here are some ideas of what you can make using a crochet rectangle: 

Scarves: A long, narrow rectangle can be fashioned into a stylish scarf. You can use different stitch patterns, colors, or yarn textures to create unique designs. 

Table Runners: Crocheted rectangles can be sewn or joined together to make beautiful table runners. Experiment with various patterns and colors to match different decor styles. 

Blankets or Afghans: Join multiple rectangles to form larger panels for blankets or afghans. Mix and match colors or stitch patterns for a personalized touch. 

Pillows or Cushion Covers: Sew two rectangles together, stuff them with pillow inserts, and create decorative throw pillows or cushion covers for your home. 

Tote Bags: Fold a rectangle in half, stitch the sides together, add handles, and create a simple yet stylish tote bag. 

Placemats: Crochet rectangles can be used individually or joined to make placemats. They offer a handmade touch to your dining table. 

Wall Hangings: Embellish a crochet rectangle with fringes, tassels, or appliques and hang it as a decorative wall hanging. 

Shawls: Larger rectangles can be used as the base for crochet shawls or wraps. Add lace edging or decorative borders for an elegant finish. 

These are just a few ideas to inspire you. Rectangles in crochet can be a starting point for various projects, and with creativity and imagination, you can turn them into a wide range of items for both practical use and decoration. 

How to crochet a 3d rectangle? 

A 3D rectangle would mean a cuboid, with 4 sides being rectangular and longer and the last 2 opposite sides smaller like a square.  

We will similarly start off the same way as the rectangle above, then continue into rounds and end off with the same rectangle covering the last side. The pattern is as follows: 

Row 1: Chain 7 

Row 2: Sc6, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

Turn and rotate whole piece, sc1 in last st, then place stitch marker here. Continue in rounds now, instead of rows.  

Round 1: Sc1 in last st (as mentioned above), sc2 along side, 2sc1 in corner, turn and rotate, sc4 along bottom, 2sc1 in corner, turn and rotate, sc3 along side, turn and rotate, sc6 - 20st  

Round 2-3: Sc20 in a round - 20st  

Using a separate new piece of yarn, create the same rectangle again:  

Row 1: Chain 7 

Row 2: Sc6, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

Add stuffing to the first piece that has 5 sides, then close up the last side with the second rectangular piece by sewing them together using whipstitch. I have used this method to create a couch and a similar more long-winded version to create an ice cream truck. 

How do you crochet a rectangle basket? 

Creating a crocheted rectangle basket involves making two rectangular panels and then assembling them to form the sides and base of the basket. This is much like the previous example I gave on crocheting the cuboid but with one side exposed to form a basket. Complete the same pattern above but with 5 sides only and work with a much larger rectangle as the base. So instead of starting with a chain of 7, you might want to go up to a chain of 20, depending on how large you want your rectangle basket to be! 

Feel free to customize your rectangle basket by adjusting the stitch pattern, size, or adding embellishments to match your preferences or home decor. This basic pattern provides a framework for creating a crocheted rectangle basket that can be adapted and personalized in various ways. 

How to use crochet rectangle in amigurumi? 

Crocheting rectangles can be a valuable technique in amigurumi to create various components like limbs, bodies, and more. Here's how you can use crochet rectangles in amigurumi: 

Body: Larger rectangles can form the base of the amigurumi body. Fold or sew the rectangle to create a tubular shape and stuff it to form the body. You can adjust the length and width to suit the design. 

Clothing or Accessories: Rectangles can be used as a starting point for creating clothing or accessories for the amigurumi, such as scarves, skirts, or blankets. 

Vehicles: Joining up multiple rectangles into a cuboid shape can be made into small vehicles like an ice cream truck, which is the example I have below here! 

Conclusion of how to crochet a rectangle 

With a few simple steps, by chaining the desired length, stitching rows or rounds in a preferred pattern, and watching the rectangle take shape. Whether it's the base of a cozy blanket, the foundation of an amigurumi friend, or the starting point for various accessories, mastering the art of crocheting rectangles unlocks a world of possibilities in the realm of crochet.

Crochet squares serve as a fundamental crochet shape in various patterns and are often used as components to create larger projects by joining multiple squares together. They can be worked in continuous rounds or joined afterward to form intricate designs or patterns, offering endless possibilities for crafting unique and visually appealing crochet pieces. It is a great way to start learning crochet as it is easier to pick up as opposed to say crocheting a circle.

What is a crochet square? 

In crochet, a square refers to a geometric shape formed by working stitches in rows or rounds to create a four-sided figure with equal sides and four right angles. Crochet squares are versatile and widely used in various projects, including blankets, afghans, coasters, motifs, or as building blocks for larger designs. These squares can vary in complexity, size, and design, depending on the pattern and stitches used.  

What is a crochet square called?  

In crochet, a square motif or shape can be referred to simply as a "crochet square." However, depending on the pattern, design, or intended use, crochet squares may also have specific names based on the stitch pattern or technique used to create them. 

Some crochet square patterns have distinct names based on their appearance or design, such as "granny squares," which typically consist of clusters of stitches in a traditional motif style.  

How to crochet a square step by step? 

Let’s move onto making a flat 2D square, which can be used in making simple coasters, for my amigurumi, I have made them into mini capes. We will start off simple with a foundation chain and crocheting into rows, then end off with single crocheting all around 4 sides of the square. See the following pattern: 

Row 1: Chain 5 

Row 2: Sc4, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

If you simply end off at Row 5, you will get a basic square shape that is the easiest to crochet up. In the next part, I ended off with an additional step to crochet around the basic piece above just to tidy it up and make a neater square, still using single crochet stitches.  

How to crochet a square single crochet? 

Follow the steps mentioned above with Rows 1-5 and then continue with the instructions below.  

Turn and rotate whole piece, sc1 in last st, then place stitch marker here. Continue in rounds now, instead of rows.  

Round 1: Sc1 in last st (as mentioned above), sc2 along side, 2sc1 in corner, turn and rotate, sc2 along bottom, 2sc1 in corner, turn and rotate, sc3 along side, turn and rotate, sc4 - 16st  

The final completed square should have 16 st in the round, with the edges in all sides tidied up nicely. 

How to crochet a square around a circle? 

This method does not technically give a very nice uniform perfect square, but it follows the same concepts as crocheting a triangle around a magic ring. It basically involves crocheting around a magic ring and making selected stitches fatter to simulate the corners of a square. Go ahead and try until Round 4 to get a small triangle, I wrote up to Round 5 so that the number pattern is easier to understand and continue if you want to make the square larger.  

Round 1: Magic ring sc4 – 4st 

Round 2: 4sc4 – 16st  

Round 3: (Sc3, 4sc1) x 4 – 28st 

Round 4: (Sc6, 4sc1) x 4 – 40st 

Round 5: (Sc9, 4sc1) x 4 – 52st 

How do you crochet a granny square step by step? 

I just decided to include this in for completeness and because there are folks who love crocheting granny squares. I definitely do not profess to know anything about crocheting granny squares since my passion is in crocheting amigurumi. So I am going to leave this to the experts and link out to someone who would be better equipped in showing you the step by step instructions for a granny square below. 

What is the easiest square to crochet? 

Out of the 4 different methods mentioned above on how to crochet a square, the easiest is most probably the first one because it just involves crocheting a foundation chain, turning and crocheting down the chain and then subsequently in rows. Ending off with the second part by crocheting all around the main piece helps with making the final piece neater and it’s pretty easy as well.  

Why is my crochet square not square? 

There could be several reasons for why your crochet square is not turning out perfectly. It could be from inconsistent tension while crocheting, which distorts the square shape. Irregular stitch count on the square sides can cause the square to skew as well, which happens when missing or adding stitches. Likewise, uneven increases or decreases in the pattern can lead to a non-square shape.  

Why is my crochet square not flat? 

Apart from the same reasons I mentioned above which include inconsistent tension, irregular stitch counts and uneven increases or decreases, this could happen depending on the method you choose to crochet a square. If you decide to crochet a square around a magic ring, the 4 single crochet inside one stitch might cause the square to pucker a bit at the corners, this can be rectified by trying taller stitches with more gaps like a double crochet square.  

Why is my crochet square curving? 

Much like the previous question, the crochet square is not flat but instead looking like it is curvy or wavy might be from squeezing too many increases in the stitch in a round. Also, if you crochet with too tight tension when starting out, the corners of the square will curve up as well. This can also happen if the crochet hook you pick is way too small for the yarn weight and the stitches become too tight and the fabric too dense, causing the square to curl. 

How do you keep crochet squares straight? 

Some simple ways to keep the crochet squares straight is to maintain consistent tension while crocheting and to use the same yarn weight and type throughout the whole project. Consistency in materials and tension helps maintain uniformity in your squares. 

Also remember to count your stitches regularly, especially at the end of rows or rounds, to ensure you have the correct number of stitches on each side of the square, this helps with straight edges and prevents irregularities. You can check out this article on “Stitch Counting Made Easy: A Beginner's Guide to Counting Stitches in Crochet” for more information.  

Lastly, when following a pattern that requires shaping within the square, ensure you're making the correct number of increases and decreases as per the instructions. Evenly spaced shaping prevents the square from becoming distorted. 

Also, for crocheting squares with taller stitches like double crochet stitches and to maintain straight edges every time, this method is quite useful to try out, just click over to here.  

How many stitches do you need to crochet a square? 

This really depends on a few factors about the square you want to crochet. For one, the number of stitches depends on the size of the square. A larger square generally requires more stitches than a smaller one. Also, the type of stitch used and its height (single crochet, double crochet etc) affects the number of stitches required. Some stitches may create shorter or taller rows, affecting the stitch count. If you are following a specific pattern, the designer will typically specify the number of stitches needed for each row or round to achieve the square shape.  

How do you crochet a small square? 

For a small square, you could follow the easiest example I stated above which is a 5x5 square or the pattern below:  

Row 1: Chain 5 

Row 2: Sc4, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

This is technically using the shortest stitch, the single crochet stitch (apart from slip stitch) and a square of 5x5 is as small as it gets. Shorter foundation chains do not make for uniform perfect squares so I did not make the pattern any shorter or smaller. 

How to crochet a large square? 

By following the same steps as for the small square above, you could make a larger square, just make sure the number of chains in the foundation chain and the number of rows tally. So in the case of a larger square that you want to maintain all single crochet stitches, you could try a pattern like this: 

Row 1: Chain 10 

Row 2: Sc4, ch1 and turn - 4st 

Row 3-10: Repeat Row 2 – 4st 

While on the other hand, if you choose to crochet with taller stitches like double crochet stitches, then technically the height of the row will double that of single crochet stitches, so to achieve the same large sized square, you could finish it in a shorter time period! 

How long does it take to crochet a square? 

The time it takes to crochet a square can vary widely depending on several factors: 

Size of the Square: Larger squares naturally take more time than smaller ones. A small square might take anywhere from 10 minutes to an hour, while a larger square could take several hours or more. 

Complexity of the Pattern: Some square patterns involve more intricate stitches or techniques that take longer to complete compared to basic stitches. Like granny squares!  

Crocheter's Skill Level: Beginners might take longer to crochet a square compared to experienced crocheters who are more familiar with the stitches and techniques. 

Concentration and Speed: The individual crocheter's speed and ability to concentrate on the project can also affect the time taken. Some crocheters work faster than others. 

Interruptions and Breaks: Interruptions or breaks during the crocheting process can extend the overall time taken to complete a square. 

As a rough estimate, a simple, small-sized square worked with basic stitches might take anywhere from 30 minutes to an hour for an average crocheter. However, larger or more intricate squares can take several hours or even days to complete, especially if the pattern involves complex stitches or a larger size. 

The time it takes to crochet a square is highly individual and can vary based on these factors and the specific project's requirements. 

How to crochet a cube? 

The 3D version of a square would be a cube with all 6 sides being the same size as the square. We will similarly start off the same way as the square above, then continue into rounds and end off with the same square covering the last side. The pattern is as follows below: 

Row 1: Chain 5  

Row 2: Sc4, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

Turn and rotate whole piece, sc1 in last st, then place stitch marker here. Continue in rounds now, instead of rows.  

Round 1: Sc1 in last st (as mentioned above), sc2 along side, 2sc1 in corner, turn and rotate, sc2 along bottom, 2sc1 in corner, turn and rotate, sc3 along side, turn and rotate, sc4 - 16st  

Round 2-3: Sc16 in a round - 16st  

Using a separate new piece of yarn, create the same square again:  

Row 1: Chain 5 

Row 2: Sc4, ch1 and turn - 4st 

Row 3-5: Repeat Row 2 – 4st 

Add stuffing to the first piece that has 5 sides, then close up the last side with the second square piece by sewing them together using whipstitch. Use this method of crocheting a cube to make mini amigurumi presents or even amigurumi furniture. 

Conclusion of how to crochet a square 

Crocheting a square is a great way to start off your crocheting journey as it is the easiest to pick up. Not only that, it is a great building block for larger projects with more intricate stitch patterns, colours and designs. Whether you crochet blankets, garments or amigurumi, learning how to crochet and vary your squares is crucial in bringing your crochet projects to the next level! For amigurumi lovers, you can progress onto 3D shapes from crocheting a square as well!

Crocheting a triangle may seem like a daunting task, but it's actually quite simple once you get the hang of it. Whether you're looking to make a shawl, a bikini top, or a decorative piece, crocheting a triangle is a versatile skill that can be used in a variety of projects including amigurumi. So, let’s dive right in – there are 6 ways to crochet a triangle to check out below! 

Table of Contents Show

What is a crochet triangle? 

A crochet triangle refers to a shape created using crochet techniques that results in a three-sided polygon with three angles. There are several methods for crocheting a triangle, including crocheting in rows or rounds, and using different stitch patterns. As I will be going through in the next section, each triangle made using a different method looks slightly different.  

How do you crochet a simple triangle step by step? 

This method here is the easiest to try out first and is the first example in the 6 examples below. I thought to just illustrate it here in broken down steps before moving onto the other examples.  

The first method of crocheting a triangle involves using decreasing crochet stitches to start from a chain and then decreasing the length down. Do note that the chains and turns at the end of the rows do not add to the final stitch count. See the pattern that follows below: 

Starting the triangle 

Start off with a simple slip knot.  

Row 1: Chain 5 

This is the foundation chain to start off with.  

Continuing the triangle 

Row 2: Working into 2nd ch from hook, sc4, turn - 4st 

Row 3: Skip 1st st, sc3, turn - 3st 

This simple example here involves making a small triangle, which has been determined by the first foundation chain above when we settled on just a chain of 5.  

Finishing up the triangle 

Row 4: Skip 1st st, sc2, turn - 2st 

Row 5: Sc1 and end off – 1st 

The last part involves reducing the number of stitches in each row until we are down to just one stitch. For the purposes of making this simpler, I did not involve any decreases in stitches but rather just skipping stitches to reduce the stitch count in each row.   

What are the different types of crochet triangles? 

The above example counts as a single crochet triangle and the first method involved a decrease in crochet into a triangle. I will repeat the short pattern below for the first example and then continue with the other examples thereafter.  

For the 6 examples of how to crochet a triangle, they involve decreasing stitches into a triangle, increases stitches into a triangle, increasing stitch heights into a triangle, using a magic circle to crochet a triangle, using picot stitches to make triangular edging and finally a little bit about a triangle granny square.  

How do you crochet a single crochet triangle? 

The first 2 examples are the easiest to start off with and to follow so I will list them first with their corresponding short patterns and step by step pictorial instructions. Like I mentioned, the first pattern has been mentioned above and is repeated in entirety below  

How do you decrease a crochet into a triangle? 

The first method of crocheting a triangle involves using decreasing crochet stitches to start from a chain and then decreasing the length down.  

Row 1: Chain 5  

Row 2: Working into 2nd ch from hook, sc4, turn - 4st 

Row 3: Skip 1st st, sc3, turn - 3st 

Row 4: Skip 1st st, sc2, turn - 2st 

Row 5: Sc1 and end off - 1st 

How do you increase a triangle in crochet? 

Then the second method involves starting from a short chain and increasing the length up. It looks pretty similar to the previous method to create a triangle. Often, these triangles can be made into ears for some animal amigurumi like making cats. The pattern is as follows: 

Row 1: Chain 2  

Row 2: 2sc1 into 2nd ch from hook, ch1 and turn - 2st 

Row 3: 2sc1, sc1, ch1 and turn - 3st  

Row 4: 2sc1, sc2, ch1 and turn - 4st 

Row 5: 2sc1, sc3 and end off - 5st 

How do you crochet a triangle with taller stitches? 

This third method is my favourite method for crocheting a triangle and it involves increasing the stitch height all along a chain. Using this method creates the nicest and most even looking triangle but the bigger it gets, the more obvious the gaps are in between the tall stitches. It is still great for creating smaller triangles. See the pattern below: 

Row 1: Chain 5  

Row 2: Sl st 1 in 2nd ch from hook, hdc1, dc1, tr1 - 4st 

How do you crochet a triangle with a magic circle? 

This method does not technically give a very nice uniform perfect triangle but it becomes more apparent as it gets bigger. It basically involves crocheting around a magic ring and making selected stitches fatter to simulate the corners of a triangle. Go ahead and try until Round 4 to get a small triangle, I wrote up to Round 5 so that the number pattern is easier to understand and continue if you want to make the triangle larger.  

Round 1: Magic ring sc3 – 3st  

Round 2: 4sc3 – 12st  

Round 3: (Sc3, 4sc1) x 3 – 21st 

Round 4: (Sc6, 4sc1) x 3 – 30st 

Round 5: (Sc9, 4sc1) x 3 – 39st  

How do you crochet triangle edging? 

This method involves using a picot stitch to create a sharp point like a triangle. It does not create the prettiest triangle but I have used this in many ways to create pointed tips seamlessly and it is commonly used for triangle edging. I have used this method to crochet mini masks and even hairstyles for my amigurumi.  

Row 1: Ch5 

Row 2: Insert into 2nd ch from hook, sc1, (sc1, ch3, sc1 down side ch), sc1 in next main st, sc1 - 4st 

How to crochet a triangle granny square? 

I just decided to include this in for completeness and because there are folks who love crocheting granny squares, so you could make a granny triangle. I definitely do not profess to know anything about crocheting granny squares since my passion is in crocheting amigurumi. So I am going to leave this to the experts and link out to someone who would be better equipped in showing you the step by step instructions for a granny triangle.  

How to crochet different sizes of triangles? 

Crocheting triangles can be a fun and creative way to add interesting shapes to your projects. Depending on your project, you may need to crochet triangles of different sizes. Here are some tips on how to crochet triangles of varying sizes.  

How do you crochet a small triangle? 

If you want to crochet a small triangle, you can start with a small number of stitches for the foundation chain for the first decreasing stitches method or end off with fewer rows or rounds with the increasing stitches method and magic ring method respectively. For the method with taller stitches, likewise, start off with a smaller number of stitches in the foundation chain.  

How to crochet a long triangle? 

To crochet a long triangle, you can use a similar technique to crocheting a small triangle above, but with more stitches. For example, you can start with a chain of ten stitches for the first method, then slowly decrease down to 9 stitches and so forth until you reach the tip of the triangle. On the other hand, if you are crocheting the increasing stitches method, then continue into Rows 5 and beyond until Row 10 where you end up with 10 stitches.  

How to crochet a wide triangle in this case is similar to how to crochet a long triangle as I mentioned above since the triangle patterns suggested in this article are all equal in length on all sides. There are other variations of triangles where the sides of the triangle may not be uniform in length but that is not being covered here.  

What can you make with a crochet triangle? 

Crocheting a triangle can open up a world of possibilities for your next project. Crochet triangles can be used for a variety of projects such as shawls, wraps, bikini tops, bags, and shaping in clothing. Here are a few ideas to get you started: 

Bunting 

A string of crochet triangles can make a beautiful bunting to hang up for a party or as a decoration in your home. You can use different colours and patterns to make it stand out.  

Shawl 

Crochet triangles can be used to make a shawl. You can either make multiple triangles and stitch them together or make one large triangle and fold it over to wear as a shawl.  

Bra Cup or Bikini Top 

Crochet triangles can be used to make a bra cup or a bikini top. You can make multiple triangles and stitch them together to create the desired shape.  

Decorative Edging 

Crochet triangles can be used to make a decorative edging on a blanket or a pillowcase or even a bag. You can stitch them together or sew them on separately.  

Amigurumi Detailing 

Crochet triangles can be used to make amigurumi detailing on a stuffed animal or a doll. I have done this for my amigurumi’s masks or even hairstyles. 

Crocheting triangles is a versatile technique that can be used in a variety of projects. The possibilities are endless, so get creative and see what you can come up with! 

What are some other shapes similar to crochet triangles? 

Crochet triangles are a versatile shape that can be used for a variety of projects. However, if you're looking for something a little different, there are other shapes that are similar to crochet triangles that you might want to try. 

Diamond and oval 

Diamonds and ovals are two shapes that are similar to crochet triangles. Like triangles, they can be worked in rows or in the round, and they can be used for a variety of projects. Diamonds are great for creating intricate patterns, while ovals are perfect for creating curved edges. For diamonds, simply combine the second increasing method above and then continue into the first decreasing method to get a diamond! As for a detailed breakdown on crocheting ovals, this article on “8 extraordinary ways on how to crochet an oval pattern” will show you all the different ways to do it. 

Cone, pyramid and biconvex shapes 

Another set of shapes similar to crochet triangles are cones, pyramids, and biconvex shapes. These shapes are three-dimensional and can be used for a variety of projects, from hats to stuffed animals.

What is a crochet semi-circle? 

A crochet semi-circle is a half-circle shape created by crocheting in increasing half rounds from a magic circle, to form a curved, semicircular piece. It's a partial circle shape that can be used in various projects, from decorative elements to garment design. 

To crochet a semi-circle, you typically start with a magic ring and then crochet along the curve of the magic ring without completing a full circle. The number of increases crocheted along the curve determine the width and curve of the semi-circle. 

Can you crochet a semicircle for beginners? 

Yes it is fairly simple to do, if you know how to start off with a magic ring. If you do not know how to crochet a magic ring, start off with this article “24 Easy Peasy things you need to know about Magic Ring in Crochet”. Alternatively, you could start off with chain 2 and single crochet method to create a semicircle with pretty much the same outcome at the end. 

How do you crochet a half circle? 

Making a semi-circle is essentially made up of half a circle or in this case, half a magic ring. Instead of how you would normally increase in the subsequent rounds to form a larger circle, this time, at the end of the row, chain and turn the whole piece. Then working along the curve, continue increasing the stitches and then at the end of the row, chain and turn the whole piece again. The short pattern example is answered with the next question.  

How do you crochet a semi circle? 

Here is a short pattern example on how to crochet a simple small semi circle.  

Round 1: Magic ring sc5, ch1 and turn - 5st 

Round 2: 2sc5, ch1 and turn – 10st 

Round 3: (Sc1, 2sc1) x 5 – 15st  

How to single crochet a half circle? 

Basically a crochet semicircle, or a semi-circle, or a semi circle is the same as crocheting a half circle. I thought I just include it here in case there is any confusion. The pattern listed below is the same for a half circle as it is for the semicircle above.  

Round 1: Magic ring sc5, ch1 and turn - 5st 

Round 2: 2sc5 – 10st 

Round 3: (Sc1, 2sc1) x 5, ch1 and turn – 10st 

Also, the example above specifically only involves single crochet stitches, while in the next 2 parts, we will be working with the same general pattern but with taller stitch heights and their corresponding turning chains as well.  

How do you crochet a half circle with HDC? 

To crochet a half circle with hdc, follow the single crochet pattern above but this time with taller stitches and an accompanying turning chain of 2.  

Round 1: Magic ring ch2, hdc5, ch2 and turn – 5st  

Round 2: 2hdc5, ch2 and turn – 10st  

Round 3: (Hdc1, 2hdc1) x 5, ch2 and turn  – 15st  

Continue the pattern as intended until you reach the size desired.  

How to make a double crochet semicircle? 

To crochet a half circle with dc, follow the single crochet pattern above but this time with taller stitches and an accompanying turning chain of 3.  Round 1: Magic ring ch3, dc5, ch3 and turn – 5st  

Round 2: 2dc5, ch3 and turn – 10st  

Round 3: (Dc1, 2hdc1) x 5, ch3 and turn  – 15st  

Continue the pattern as intended until you reach the size desired. 

How to crochet different sizes of half circles? 

To crochet different sizes of half circles, tweak the patterns above based on the number of stitches in the starting round, the number of increases in subsequent rows and of course the stitch heights. All these crochet changes will help with experimenting in different variations in sizes of your crochet semicircles or crochet half circles.  

How do you crochet a little half circle? 

To crochet a little half circle, consider starter off with a smaller magic ring initially in the first round, fewer subsequent rounds and using single crochet stitches which is the shortest form of stitches. The fewest number of rounds you could work into a crochet semicircle is probably just 2 rows, including the initial magic ring and just the second row of increases.  

How do you crochet a large half circle? 

As for crocheting a larger half circle, you could increase the number of stitches in the starting magic ring, increase the number of subsequent rows and finally, use taller stitches like double crochet or treble crochet stitches. All these can increase the size of your semicircle, for a detailed example, see the pattern below: 

Round 1: Magic ring sc5, ch1 and turn - 5st 

Round 2: 2sc5, ch1 and turn – 10st 

Round 3: (Sc1, 2sc1) x 5, ch1 and turn – 10st 

Round 4: (Sc2, 2sc1) x 5, ch1 and turn – 20st  

Round 5: (Sc3, 2sc1) x 5, ch1 and turn – 25st 

Continue the pattern as intended until you reach the size desired. 

What are some crochet semicircle shape variations? 

For this section, we will be talking a bit about different types of semicircle shape variations, both in 2D and 3D forms. For the 2D shapes, we will talk about circles and also ovals which can appear quite similar to semicircles. As for the 3D versions of a semicircle, that would include a hemisphere and a hemicylinder. Read on to see what I mean.  

How to crochet a circle? 

Crocheting a circle is very similar to the initial semicircle pattern above. There is no chain and turn and it involves working continuously in rounds. I have written a short pattern below which is similar to the initial semicircle pattern, but it is just the circle version.  

Round 1: Magic ring sc5, ch1 and turn - 5st 

Round 2: 2sc5– 10st 

Round 3: (Sc1, 2sc1) x 5 – 10st 

Round 4: (Sc2, 2sc1) x 5 – 20st 

For a full breakdown of all the variations involved in crocheting a circle, check out this article “14 useful things you need to know about How to Crochet a Circle”.  

How to crochet an oval? 

An oval shape is very similar to semi-circle or a half circle shape. In fact, some of techniques involves in crocheting an oval can product a final shape quite similar to a semi-circle. There are 8 different ways I have found that can be used to produce a flat oval shape or a pointed oval shape. The closest one to a semicircle is listed below with its pattern: 

Crocheting an oval with a foundation chain 

Row 1: Ch9 

Row 2: Sc2, hdc1, dc2, hdc1, sc2, go around chain and rotate, 

Row 3: Sc2, hdc1, dc2, hdc1, sc2 

As for all the other different techniques to crochet an oval, check out this article “8 extraordinary ways on How to Crochet an Oval Pattern”.  

How to crochet a hemisphere? 

Here we are moving onto some 3D shapes. So, a 3D version of a circle is technically a sphere, so by extension, a 3D version of a semicircle is a hemisphere. This is fairly simple to achieve, it involves the first part of crocheting a sphere but stopping midway to get half of the sphere. Below I listed a short sphere pattern and then a hemisphere pattern.  

Sphere pattern:  

Round 1: Magic ring sc5 - 5st 

Round 2: 2sc5 - 10st 

Round 3: 2sc10 - 20st 

Round 4: Sc20 - 20st 

Add stuffing to the sphere.  

Round 5: Sc2tog10 - 10st 

Round 6: Sc2tog5 - 5st  

Close up in FLO in last round. 

Hemisphere pattern: 

Round 1: Magic ring sc5 - 5st 

Round 2: 2sc5 - 10st 

Round 3: 2sc10 – 20st 

Round 4: Sc20 - 20st 

You could continue on and make a larger hemisphere. To close it up, crochet a separate piece with the same Rounds 1-3 to form a flat circle and cover up the hemisphere above by sewing both pieces together.  

How to crochet a half sphere? 

Crocheting a half sphere is the same as crocheting the hemisphere above. For a larger pattern you could also try to continue the above pattern in the 2 different ways below: 

Half sphere pattern – longer version: 

Round 1: Magic ring sc5 - 5st 

Round 2: 2sc5 - 10st 

Round 3: 2sc10 – 20st 

Round 4: Sc20 – 20st 

Round 5: Sc20 – 20st  

Half sphere pattern – larger version: 

Round 1: Magic ring sc5 - 5st 

Round 2: 2sc5 - 10st 

Round 3: 2sc10 – 20st 

Round 4: Sc20 – 20st 

Round 5: (Sc1, 2sc1) x 10 – 30st  

Round 6: Sc30 – 30st  

How to crochet a 3d semicircle? 

As for a 3D semicircle, rather than looking like a hemisphere, a 3d semicircle ends up looking like hemicylinder, if that is the right term. It basically looks like a cylinder that has been sliced down the middle, so a hemicylinder. The short pattern is below and its appearance as well. I have used this unusual shape to crochet part of a spaceship! 

Hemicylinder pattern: 

Round 1: Magic ring sc5 - 5st 

Round 2: 2sc5, ch1 and turn - 10st 

Round 3-12: Sc10, ch1 and turn, continue along the curve - 10st  

Continue until desired length of hemicylinder. 

What can I make with a semicircle crochet? 

A crocheted semicircle offers a versatile base for various projects due to its curved shape. Here are several things you can create using a crocheted semicircle: 

Shawls or Wraps: Semicircles can be the starting point for creating beautiful shawls or wraps. By adding additional rows or lace patterns, you can expand the semicircle to create a larger, flowing garment. 

Hats: Use a semicircle as the crown or top part of a hat. Adding additional stitches or rounds can transform it into the crown of a beanie or a beret. 

Rugs or Doilies: Crochet semicircles can be the foundation for decorative rugs or doilies. Combine multiple semicircles to create larger circular patterns or use them individually as decorative mats. 

Garment Elements: Incorporate semicircles into garments as decorative elements or yoke patterns for sweaters or tops. They can be used to create unique sleeves or shoulder details. 

Appliques: Crochet small semicircles as appliques to adorn bags, clothing, or accessories. They can resemble petals for floral designs or be part of intricate motifs. 

Coasters or Placemats: Semicircles can be the starting point for creating circular coasters or placemats. Add borders or decorative elements to enhance their appearance. 

Baskets or Bowls: By shaping and stiffening the crocheted semicircles, you can create baskets or bowls for storing small items or as decorative pieces for your home. 

The versatility of the crocheted semicircle allows for creativity in design and application. Depending on your preferences and the project at hand, a crocheted semicircle can serve as a starting point for various beautiful and functional items. 

How to use crochet semicircle in amigurumi? 

In amigurumi, crocheted semicircles can be incredibly versatile and useful for creating various elements and characters. Here are some ways you can use them: 

Body Parts: Semicircles can serve as body parts for certain characters. For example, they can be used as the base for rounded animal bodies or as the curved shape of wings for birds or insects. 

Hats or Caps: Crocheted semicircles can function as hats or caps for amigurumi characters. Depending on the size and design, they can be transformed into berets, beanies, or even sunhats for amigurumi dolls. 

Clothing: Use semicircles to create clothing elements such as skirts or dresses for amigurumi figures. By varying the size and stitch pattern, you can craft adorable outfits for your amigurumi creations. 

Accessories: They can serve as elements for accessories like bags, purses, or backpacks. A semicircle can be folded or stitched to create a bag flap or a decorative part of an accessory. 

Faces: When partially stuffed and shaped, semicircles can become the rounded part of certain facial features, like cheeks or snouts, giving your amigurumi a cute and dimensional appearance. 

Tails or Fins: Use crocheted semicircles to craft tails for animals or fins for aquatic creatures in your amigurumi designs. 

These semi-circular shapes are incredibly versatile and can be adapted to suit various needs in amigurumi, adding depth and character to your creations. Remember to pin the image below if you found this article useful!
