I have an A1 long arm and I have made several sets of zippered leaders. I sewed the zipper to the attached leader and then put about 10" of lightweight duck canvas on the other leader and attached with the zipper. Now, I staple my quilts to the leader. No pins and they come off easy. The staples make holes in the leader but they last at least a year and then I just make a deeper hem and keep on going. PM me if you want further instructions.
