I think Sharon Shaumberg had a method of attaching binding where you use Elmer's school glue to hold down the binding and make it perfect before you sew it. You would need one of those really tiny glue tips things (I have one)
Elmers washes out. I personally wash every quilt before it goes out the door. I have not tried this for a binding but will be this weekend on a Downey quilt. You use a very thin strip of glue and then iron it to dry it and make it stick. Do not use a lot, you don't want it to go through the fabrics. I have used it to hold my quilt labels onto the quilt in the right position as I hand stitch them down. I got tired of getting my hands torn apart with pins!!! Remember, tiny amount of glue, press w/ hot iron, holds things together until you sew.
