I haven't had a wrinkle or pucker worry since I started using Elmer's School glue. The fabric isn't going anywhere and it's so simple to pull apart and if I need to. I had quilt basted with the glue for over 3 months. I decided I didn't like the backing so just pulled it right off, re glued the backing I wanted. The glue washes out completely, non toxic. It's really a heavy starch product.
