Ok. Decided to give this a try. My conclusion is that I prefer my spray baste to glue. I sandwiched my quilt on the floor. Even though I stood above the quilt and lightly drizzled glue on the backing, I didn't know until I went to pick it up, despite how lightly I applied the glue, it went through the fabric. So I will stick to my spray adhesive. I use my tempurpedic mattress to sandwhich on and I can't afford to get glue going through the fabric and if I'm careful with spray basting I don't have to worry about overspray. And by sandwiching on my mattress, it saves my back.
