Tutorial: Sew a Keyhole Neckline with a Facing
Since I keep trying to explain facings to friends (and keep feeling like Iām failing miserably), I decided to do a longer tutorial, after all, about how to I use a facing to sew keyhole necklines on simple medieval-style tunics. This is an attractive and sturdy neckline for LARP/Dagorhir/SCA garb. Iāve used it on literally hundreds of tunics.
This tutorial ended up getting pretty long and scary, but donāt worry: this is not a complicated process. Itās just hard to explain over the internet. So-- letās go!
What is a facing, anyway?
A facing is just an extra bit of fabric that you sew to the edge of your garment and fold down to conceal a raw edge. I use them on necklines, instead of folding the edge down in a traditional hem.Ā If you donāt get the concept, @vintage-aerith has a great tutorial here.Ā Facings produce very sturdy, flat, and non-bulky edges.
For example, this tunic has a keyhole neckline finished with a self-colored green facing. The edge of the neckline is NOT folded over and hemmed: the facing is an extra piece of fabric that was stitched on to the edge and then folded to the inside. You can see the ālowerāĀ edge of the facing-- itās the darker green line about 1.5ā³ in from the edge.Ā I then tacked the facing down with embroidery. Itās a very clean, unobtrusive finish.
This tunic has a very fancy external orange facing, combined with a collar! The process is very similar to above, but the facing is flipped to the outside. This is an easy way to add color to a garment. (Forgive my dork-face and overlarge tunic-- this was for a customer whoās about a foot taller than me!)
You should use facings because:
Hemming necklines is a pain. TheĀ curve will not want to fold down flat. Facings, on the other hand, are exactly the same size and shape as the neckline, so they automaticallyĀ lay flat.
The point at the bottom of a keyhole is a nightmare to hem, and if you hem it badly, it will fray and rip, fast.
When you fold down a neckline to hem it, your neck-hole gets bigger. When weāre talking LARP/SCA/Dagorhir garb, a bigger neck-hole always means more sunburn.Ā If you use a facing, youāll get a neckhole exactly the size you planned.
Hemming stretches your neckline out. The more you handle a cut piece of fabric, the more it will stretch. A stretched out neckline = more sunburn, again. This facing method minimizes handling of cut edges, so the neckline stays nice and tight.
Facings are fast and easy once you understand what youāre doing and why. I can knock one out, start to finish, in about ten minutes. No lie.
Now that Iāve convinced you that facings rock, onward!
1. Make Your Facing Pattern
Youāll first need a pattern for your facing, and to make that, you need to know what size youādĀ like your finished neckline to be. I recommend a neckline thatās made of a circle thatās aboutĀ 5.5ā³ in diameter and a 3ā³ slit, like this. This is juuust big enough that it will pull over most heads.Ā
Draw your 5.5ā³ circle on a bit of scrap fabric. (I traced a saucer onto a sheet from a charity shop. Pure class, me.) This will be the hole your head goes through.
But, you protest, a 5.5ā³ circle only has a 17.25ā³ circumference! Thatās way too small for anyoneās head! Well spotted: weāll add a 3ā³ long slash down the center line so you can fit your head through.Ā
Now weāll mark the center and shoulder line.Ā Since your tunic has a front half and a back half, youāll be sorely tempted to put half your neck-circle on the front and half on the back.
But if you do this, your tunic will be really uncomfortable! Your neckline will constantly creep forward around your shoulders. This is because most of your neck is actually in front of the shoulder seam, so 2/3rds of your circle-- about 3.66ā³ on a 5.5ā³ circle-- should go in front of your shoulder.
Add 1.5ā³ around the edge of the hole and and around the slash.Ā
Cut the fabric out along the outer line.
Cut out the center hole, and cut down the slash. Note that youāre just cutting the slash open with one pass of your scissors-- youāre not trimming anything away.Ā
Now you have a mock-up for your facing. It should look something like this. (Mine is super ugly because Iām traveling and only have terrible blunt scissors with me.)
Pull it on. Can you fit this over your head? Does it lie comfortably?Ā If you canāt get this over your head, cut the slash a tiny bit longer and try again. If that doesnāt work, make the hole a tiiiiny bit larger.Ā Remember that a smaller neckhole is better (sunburn!).
Donāt be fooled by my weird face-- I am happy, because mine fits okay! Iāll now trace my mock-up onto a bit of sturdy poster board, making sure to mark the center front, back, length of the slit, and shoulder seams with notches.
The front white piece is my facing pattern, which I use to trace out the facing piece on fabric, ie, the background piece in olive green. Note that the fabric facing does NOT have the hole cut out. This is important!
Lay your new pattern on a bit of your fabric. Using chalk or a fabric-marking pencil, trace it all the edges and mark all the notches. Cut along the outer line until your facing piece looks like the dark shape in the photo above.
Hereās where it gets tricky, though: you wonāt cutĀ the interior circle, yet. This is because that inner edge isnāt really an edge at all: itās your stitching line. When youāre stitching your facing onto your tunic, your needle will follow that inner line that youāve chalked onto your fabric. See how in the photo above thereās a line marked in yellow chalk on the dark olive green facing? Thatās the stitching line, so DO NOT CUT THE CENTER HOLE OUT IN YOUR FACING.
Similarly, DO NOT CUT A HOLE IN YOUR TUNIC YET. We wonāt cut either hole until the facing is stitched to the tunic. Thatās right-- it will look and feel really weird, but trust me, thereās a good reason for it.
3. Finish the Edge of Your Facing
The outer edge of your facing will fray if you donāt do something to prevent that, so take a moment to serge or zigzag around the edge of your facing piece. Itās way easier to do this before you stitch the facing onto your tunic.
4. Stitch Your Facing Onto Your Tunic
Okay, so. I like to start by sew the neckline on my tunic before I do anything else. That way, if I screw it up, I havenāt wasted time (or fabric) by adding sleeves and gores and stuff.Ā
Note how, in the picture above, no holes have been cut in the facing or the torso panel. This is not a mistake. Why arenāt you cutting the holes, you might ask? Well, fabric cut along curves stretches. Badly. This is bad news if youāre trying to match the hole you cut in your tunic to the hole you cut in your facing. Getting them to match requires a ton of pinning and fussying and delicate handling. I hate pinning and fussing, so I sew my facing to my tunic before I cut any holes. This way, everything is stabilized nothing can stretch out. Cool? Cool.
Now, my torso panel is one long rectangle, which makes up the main front and back of my tunic-- thereās no shoulder seam. Fold your tunic in half both ways and use your iron to crease these folds. These creases now mark your shoulder line and center lines. Youāll use them to line up your facing.
Lay your facing onto your tunic, rightĀ sides (ie, outsides) together. Make sure to match facing to the tunicāsĀ center front, back, and shoulder seams. Remember how 2/3rds of yourĀ neckline will be on the front of your tunic? Check that, now. When your facing lays straight and flat andĀ properly positioned on your tunic, pin it in place.
Youāll now slowly stitch through both layers along the line you marked. The slash is a little different, though, so see the picture below for an explanation of how to stitch around it.
The stitching travels around the slash, with about 1/4ā³ toĀ 1/8ā³ between the lines. The bottom of the slash should be crossed by just 1 stitch. If you use more stitches, this point will pucker when you try to flip it to the inside.
Once youāve stitched along the entire stitching line, youāll finally cut the neckline open.
Be extra careful cutting the slash open. Youāll cut through the gap between the two rows of stitching, stopping just shy of the stitch at the very bottom of the slash.
Okay. So, youāve got your facing sewn to your tunic, but all the raw/cut edges are still exposed. To fix that, youāll now fold the facing to the wrong side (ie, the inside), so the raw edge will be hidden inside the fold. This can be a little tricky, so be patient and use plenty of steam with your iron. To turn the points out, use something pointy but blunt, like a big bamboo knitting needle, to poke them right-side-out.
Once youāve got your facing turned to the inside of your tunic, iron it well so the edge of the neckline is flat and crisp.
Hooray! All thatās left, now, is topstitching through the tunic and the facing in matching thread so your facing wonāt creep back out to the right side. I like to use two lines of topstitching-- one 1/8ā³ from the edge of the neckline, and another 1ā³ from the edge of the neckline. Make sure youāre catching the edge of your facing!
Hooray, you did it! That wasnāt so bad, was it? And look how sturdy and clean your tunicās neckline now looks. That keyhole is never going to rip, I tell you that.
Huge thanks to Stellaria for writing the original tutorial that taught me how to do facings, and for putting up with my hare-brained innovations on her methods. Stell is the best.Ā
