Oh, Wonder Tape. I love you so. My days of fabric slipping around when I try to hem are over! I used Wonder Tape on all hems in this project: neck, sleeves, skirt. It's one of those supplies I might have eschewed back in the day (why do you need this when you can use pins and do without it) but now that I'm an old, jaded sewist, I'll take anything that makes some regular task easier.
