- Rolled (Handkerchief) hems for finishing headwraps, hankies, chemises & anything else that needs a teeny clean hem. Fold over about 1/4" of the fabric. Put the needle through a couple threads on the fold edge, then a couple threads on the fabric side just beyond the foldover. Repeat a few times, then pull the thread up tight. The folded over bit will be completely enclosed in a little roll and you'll have a nice period edge. This works really well on gauzy fabrics that tend to bunch up from the feeder feet on a sewing machine.
Fold over about 1/4". Catch a couple threads on the fold edge and a couple on the fabric. Zigzag across a few times.
Pull the thread up tight.
Finish the whole thing and amaze your friends with your hard work.
