I am new here so Hi !!! I just learned about the basting spray but have not used it. I saw a you tube thingy about using Aqua Net spray in place of the basting spray so I tried it. I smelled so bad, too strong. My quilt did not stay together very well either. So I may try the other spray but I have not thought of using king size bed. Hope the spray does not stick to everything else, floor, maybe use newspaper?
