I don't like basting spray at all. The over spray is horrible to clean up and too much trouble to cover all exposed areas in the room. Way too many chemicals to breath too. I tried it outside, won't do that again. LOL. Until something better then washable school glue is found to baste quilts, that is the only way I will baste. I have used thread, covered safety pins, gun tacks, spray, fusible batting, and machine basting. The only other way I will baste if I don't have school glue is with Pinmoors.
