How To: Understitch

Understitching is stitching the lining or facing to its seam allowance. It is done on pocket openings, necklines, and armholes to force the facing or lining to roll cleanly to the inside and stay there. It is not visible from the outside of a garment.

It can get confusing the first time you understitch because it can be difficult to orient all of the terms and instructions with the actual pieces of fabric in your hands. Here are some photos that I hope will help!

Here’s how understitching would look on a pant pocket. The facing and lining will now roll cleanly and easily to the inside. Cool trick, huh?!Chi-Town Chinos-35
