I hesitated to offer that I only baste with Elmers Washable school glue. I gave up pin basting and thread basting. I don't like spray basting. I use cotton batting and don't dilute the glue, just drizzle from the bottle in a grid. I don't paint it on. It doesn't have to cover every inch of the quilt. I don't iron, because I am never in a hurry and can leave it overnight to dry. It does not gum up the needle and always washes out. I'm about 30 quilts in, biggest is queen sized on a Brother PQ1500. I have never had a pucker with this method, regardless of which quilting method I use.
