I admire those of you who use basting spray all the time. I make big quilts and thought if this spray stuff would work I would be in hog heaven. So I bought a can of 505 and couldn't wait to get to it. I really tried to only lightly spray one half of the back then lay the batting down, lightly spray the batting and gently put the top over. Looked good! Did the same with the other side. Looked really good! Then I found over-spray on the table, my chair, my machine, the floor, my shoes (!) and my ironing board. Then the stupid quilt shifted! That was it for me. I just have to live with the fact that I am not skillful in the art of spray basting (but I can slam-dunk a piece of furnature in nothing flat with a can of RustOleum). So I am back to pinning the snot out of my quilts. It may take more time but I don't have to spend time trying to clean up after myself.
