Leah Day shows another method. I believe it is in her Craftsy class on free motion quilting. She pins, I believe 1/2" or larger elastic to the quilt and then ties the elastic around the table legs, tightening the elastic until she has a smooth surface to pin together. If you have a friend who has the class, ask to see her method. I haven't used it as yet. I do love using the risers to make the table high enough to work on without getting a backache.
