jazzy509-- that is what I was going to suggest. I used to work at a retail fabric store and suggested this to a customer. She returned to the store a year later, I was working, recognized her, she couldn't thank me enough. The pattern had to be altered and adjusted; worked so good, she had used it several times. Just the little things in life, are amazing, even if it came from the grocery store. None of the waxy side adhered to the flannel/cotton fabric that was used. Also, the freezer pattern, can be used over and over.
Caution: spray adhesive could cause problems with sewing machine.
