I have not used the Elmer's washable glue on a big quilt so I don't know how that works. I think either the glue or 505 basting spray would probably be your best bet.
I can not stand the smell of using the spray in the house & it's too cold to go outside. I just didn't know how the elmer's glue would work on a thicker fabric like flannel.
