Sometimes a narrow hem is all you need....but how can one get a perfectly balanced turn on a curved hem? For a straight hem, using a narrow hem foot is often the easiest solution, but I have found great difficulty in using one with curves, because the fabric twists and doesn't lay properly. Follow along in these simple steps to achieve a perfect curved hem of your own!

Step 1: Stitch
My favorite use for my serger is actually not related to sewing knits or anything else, it's this: marking a seam for pressing. I find that when I use a 3-thread overlock stitch on the edge of my curved seam it presses perfectly into place. No templates, pressing rulers, or guessing required.
I don't actually trim anything off. As you can see in the photo, I align my fabric edge with the blade. If you want to trim fabric off at this step, please be sure to add some to the hem when you cut out your pattern.
The second picture is a little wavy, but don't worry, that will get pressed out when you get to step 2!
Step 2: Press
Here's a photo of the edge, pressed once. Make sure you fold over the whole stitch and leave a bit of unstitched at the (new) edge.
Step 3: Press Again
Then you can simply press around again.
Fold right at the top of the first hem for a perfect narrow hem. It is really easy to be accurate, because the serger stitches provide some body.
Step 4: Stitch!
The final step is to stitch the hem down. I like to use my topstitching foot, which has one side (left) raised to accommodate the thicker folded edge. (see photos 1 and 2) .
You could also use a blind-stitch foot (one probably came with your machine) and flip the work over so the thicker fabric folds are on the raised (right) side on that foot. (See photos 3 and 4).
Remember to choose a longer stitch length than for construction, because you're going through more layers here.
Step 5: Finished!
That's it! Simple! (And perfect....my favorite!)
