Elmer's washable school glue is wonderful for bindings. I just compared using 505 spray baste and Elmer's washable school glue on placemats the other day. The school glue worked much better for repositioning prior to tapping it with an iron. Personally I like the glue better and my arthritic hands do also. Roxanne's basting glue with the metal tip is great but found I had to squeeze too hard. My joints were aching in my right hand when I was done. I will try diluting it a bit next time. I am planning to use the washable school glue on the baby quilt I am finishing up. I will probably pin my quilt layers on my design board (a flannel lined plastic tablecloth) to pin my quilt and glue baste.
A note on the clean up after spray basting. It is washable so a damp mop should make things untacky.
