the fusible fleece is stiffer than nonfusible, I used her sugestion on a few then started using craft fuse, I was a bit worried because it looks like heavy paper but I love it, it stands up well and washes well too. I couldn't remember the number (987) one time and picked up some of what I thought it was, WRONG! it was just a tiny bit thicker but I could not sew it, when you get several layers together in a seam it just wouldn't work.
