Just pull the fabric off the batting. I used glue and decided I didn't like the backing after two weeks. I pulled the backing off the batting (cotton). I washed the backing and put it back in my stash. Elmer's School glue is a not a glue but a heavy starch. Water will dissolve it. If you dilute the glue with water to make a spray, don't use a very hot iron to press it, the starch will scorch if it is thinned.
