Go to the handicap section of any Walmart (or probably any drug store) and you will see a shower gripper for handicap folks -- it's the same thing. Once a few folks started showing up with these in classes, we all found out where to get them close to home. They are marvelous. Keep your hand well above the cutting surface, and help stabilize your fabric better too. If you want a small one to use on 6 to 61/2" rulers, there is one called the Little Gripper, available at online shops.
