I used the Elmer's glue stick with the orange top that says it is washable on the package. I put a dab about every 4 inches on 80/20 batt. I smoothed and ironed the front and then did the back. Be aware it really sticks when it is dry and if you want to reposition, you can spray with water and carefully peel up the fabric. It works well on small pieces but I think you would run into problems on a big quilt. If you got a wrinkle as you quilted, it would be pretty hard to unstick all the dabs so you could reposition.
