The Omnigrid® ruler grip is a hand-held accessory that features double suction cups for attaching to rulers or templates. It provides a steady grip on your ruler and keeps your fingers away from the rotary cutting blade while you are cutting fabrics for quilting, sewing and crafting projects. The ruler grip works on clean, smooth surface rulers or templates and attaches best on rulers or templates at least 2.25 in. in diameter. It attaches in seconds and is easy to use.
