I have glue basted a lot of quilts. I mostly use cotton batting. I sit the bottle in a bowl of hot water to make it flow. Then I drizzle it on in a way to mimic the spacing of pin basting. I might do a grid or a meander. I don’t do anything else - if I get a glob I smooth with my finger. Once one side is done I flip
over and do other side. I usually leave it to dry. I’ve never pressed to dry. I’m never in that much of a hurry. It has been a game changer for me. And the quilt is lighter and easier to maneuver with no pins
