Get a grip and rule your rulers! The Gypsy Gripper has a comfortable grip handle and two large round suction cups with handy lock and release levers. Just press the cups to any plastic ruler with a smooth solid surface, then flip the levers to lock the Gypsy Gripper in place. Now you can move the ruler quickly, and easily hold it in the exact position you want while cutting. Your ruler hand will be up and away from the fabric, out of harm’s way if you slip with the cutter.
