I would recommend standing the glue bottle in a mug with hot water before applying--this will make it flow easily. Then just try to control the amount that comes out--you won't need to use practically any pressure at all. Also, diluting the glue works better for 100% cotton, but if you're using poly batting, I wouldn't dilute it; the poly batting doesn't stick as well. I use glue basting for practically everything except for pieces that I don't want to launder, like art quilts, since I always want to wash the glue out when I'm done quilting. It's changed my life--I can glue baste a queen size quilt in about an hour. It's great!
