Once upon a time in a faraway place, I used the disolvable fuseable paper for a baby quilt. You are supposed to wash it out when you are done. Duh, I think they mean before you quilt it and bind it. I had these horrible Gobs of what seemed to me like paper mache glue. It was a disaster. Took nearly 6 washes and I was still not sure it was all out of there. I would NEVER forget to take off paper from paper piecing after that.
