I do the same as Neesie but I dilute my glue just a little. Somewhere between a 1/3 and a 1/4th. Ironing not only dries but it gets out lumps. Just be sure to do it on a cleanable floor or surface, not carpet. The glue does go thru. I had a friend try this and she tried to glue each and every inch of batting. She used way too much. Her quilt was ruined. You only need it enough to hold the layers together like a pinned quilt.
