There are two kinds of Heat and Bond. One is specifically sewable and the other isn't. I've used both. The one that is non-sewable, I would hesitate to use on a quilt as if you changed your mind and decided to sew it on after using it, it gums up your sewing machine needle. You constantly have to clean your needle. Any guess who's made that mistake??!!! The sewable type, I've just recently used it and seems to work wonderfully when I'm doing applique work using my sewing machine. Doesn't gum up the needle. I haven't tried washing the Heat and Bond piece after sewing it or iron-on only type, so I don't know how it takes to washing.
