I've used Elmer's Washable School glue for matching then sewing seams while piecing and love it! I've used it to hold binding and love it! I just used it to sandwich part of a quilt (when I ran out of spray baste) and didn't love it so much. It takes awhile to dry (quilt is too big to iron sandwich dry) and it makes hard globs in places. Also, squeezing that bottle to get a fine stream is hard work, as crazy as that sounds. If I could find a way to spray or paint it on, I might like using it more.
On the other hand, the spray baste also drives me crazy because I get overspray on the excess batting and backing (2 to 3 inches beyond the top) and on the table, floor, etc. I can wash the table and mop the floor but I hate the stickiness of the spray on the batting and backing while I'm quilting. I'm now using a piece of fabric or newspaper to block the spray but that's a nuisance, too. I think I may just not like the sandwiching part. But then who does?
