Wow! Some great info here. :) ob searched youtube when I was going to use my foot. But found out my foot doesn't fit my machine. Lol

Roll over the first two inches and pin it. Then straight stitch. Once you get that first "tail" done, then roll the rest of the fabric over your hem foot, and it will stay in position.

I make skirts all the time and rolled hems, the last step in most skirts, is the one I dread most (I might buy a serger for this very purpose). I've never had any luck with the rolled hem foot. Even my sewing teacher--who learned to sew when she was 7 years old and is 67 now--said "a person just has to be a savant to use the rolled hem foot correctly." She uses her serger for rolled hems. Since I don't have a serger, she taught me a relatively easy way to do rolled hems with a regular foot and a straight stitch. The second approach on this blogpage is exactly what my teacher taught me and what I've been doing; however, you might be more interested in the first technique, which utilizes the rolled hem foot:

Good luck and let us know how it goes!
