I'll give another opinion. I've made about 30 and know more than I want to know about them! I use Pellon ShapeFlex for fusible--it's lightweight and my LQS sells it off a roll that is 50-52? wide so less waste. Be sure you check instructions on fusible stabilizer before you fuse to any shirts that have poly in them--usually a med. heat. But have used on shirts and those sports jerseys that have woven holes. I have always used a cotton wideback for backing as most have been going off to college or "own" apt. and seem to end up getting less laundry attention and often dumped when sheets washed. I use batting also. These are great memory quilts but I burnt out on them. LOL
