I have difficulty with spray basting because I make large quilts and I have to layer them on the floor. I am 79 years old and crawling around on the floor is not my idea of fun. I bought a 4 x 8 ft. thin plywood that sits on 2 saw horses and I usually try to spray baste outside but in Central Florida in the summer that is not an option for me. I think I would pay someone to sandwich my quilt if I could find someone. I tried my LQS but the backing was all wrinkled and told me to just iron them out. That was an all day job. Never again.
