When I have used the Elmer's School Glue I just drizzled it on in a grid onto the batting, then smoothed the backing on it and let dry. Some folks iron at that point to speed the drying process but I just waited. Then flipped it over and drizzled onto the batting again and smoothed out the front. I've done this twice and it has worked well. The biggest is about 5 feet square. I didn't hand quilt, but, the needle on the machine had no problem with it, and it all washed out.
