I use the Martelli gripper ring. It's wonderful. I couldn't quilt without it, as I can't spread my fingers or exert pressure with them and so can't move the quilt in the usual way. The ring is large and it really grips! My hands are completely relaxed as I quilt. I couldn't believe how easily the quilt moved the first time I tried it. (I also use the Jennoop quilt suspension system to eliminate drag.)
