I've used Hobbs 80/20 fusable batt and I really like it. It uses a dry iron to fuse and it does wash out when you wash your quilt. You would need to make sure all the batt piece was covered though or the batt would stick to the iron. You would also need the backing fabric on or you would need to peel off the batt from your ironing surface. You can peel up and reposition and re iron on it too. If you look at the post on Confetti quilting, she has some ideas and advice there. I think the Confetti quilts are in the tutorial section?
