The Original Gypsy Gripper is designed with two suction cups that attach to any smooth ruler surface. The Gripper ensures that even pressure is applied to the cutting surface so you can relax and rest your hand comfortably over the handle. Since no death grip is required, this tool is recommended for anyone with hand issues such as arthritis and carpel tunnel. Your hand is always away from the rotary cutter so your fingers are out of harm's way, making this a must have for any new or young quilter! Note: The ruler must be at least 4in wide and 12.5in long - excluding the hang hole - to be effective. The Little Gypsy Gripper is designed with a suction cup that attaches to any smooth ruler or template surface. The Gripper ensures complete control of your small rulers and templates, and keeps your fingers out of harm's way - making this a must have for any new or young quilter! This smaller size is also perfect for long arm quilters. Hold the templates with the Little Gypsy Gripper to protect fingers when stitching. Note: The ruler or template must be at least 2.25in or larger – excluding the hang hole – to be effective.
