The Why of Sewing 7: Type Matters, Sewing Machine Needle Guide
Sewing machine needles come in a variety of sizes and types and many of the problems I see online are caused by using the wrong needle type.Β
Generally when you buy a machine it comes with universal needles in the box. Universal is a misnomer. They are very useful on a wide variety of woven fabrics. Universal needles in a size 12 are what I use for anything that is a medium weight woven.Β
Jeans needles are for heavy fabrics like denim and canvas. Generally I go up to a 14 or 16 in a jeans needle.Β
Microtex needles are super sharp. They are excellent for woven fabrics that are delicate, snag easily, or are tightly woven. I use them on silks, satin, and cotton poplins. When all else fails on a fabric, try a microtex. Microtex come in larger sizes and can be used on heavy fabrics. Microtex needles need replaced more frequently than other needle types.Β
Ballpoint or Jersey needles are the same thing, usually they are labeled as ballpoint in the US and Jersey elsewhere. Ballpoint needles are appropriate for stable knits such as cotton jersey with no or minimal stretch fibers added.Β
Stretch needles are similar to ballpoint needles in the sense that they are for knit fabrics. Stretch needles are intended for fabrics with a higher stretch fiber percentage and in addition to that they work well on more stable knits. They are what I keep in stock for working with the widest variety of knit fabrics. I usually buy 11 or 12 in stretch needles.Β
Super stretch are for super stretchy problem child knits, I have not tried these as they are relatively new on the market but I will be picking up a pack before I make swimwear again.Β
In addition to the types above there are a great many other needles with specific uses. Within each type there is a range of sizes and the needle size should be chosen to match your fabric and thread.Β
Needles are consumables and will become gradually dull as you sew. The rule of thumb is that you need to replace after roughly 8 hours of run time. If you have been using a needle for a while and things start to go wrong or the machine sound changes, the first step on troubleshooting is a new needle. Old needles can damage your fabric and are more likely to break.Β
I also want to advise against buying off brand needles and included in that category are Singer branded needles. I personally only buy schmetz and organ brand needles and I buy exclusively off wawak.com (US and Canada only).Β
