I had a problem with the bottom fabric not gliding and I put a layer of thin tissue paper under it and just ripped it off when I was finished. Worked like a charm. I didn't worry about the tissue wrinkling, but to make it stay smoother, spray the tissue (not the fabric) with a little..note I said a little... spray fabric adhesive like 505 brand before you put it on the backing fabric and it will stick to the fabric till you are done then pull off.
