I have been safety-pin basting my quilts, but the other night I was feeling adventurous/lazy so thought I would try this old can of basting spray that I have. It was stinky but it went quick and held all three layers together during my FMQ the other night. I am kind of impressed. I had no tucks with that, vs the couple I usually get with the pins. I had just resigned myself to the fact that tucks in the backing were gonna have to be design elements.
