This 12in Wave Ruler designed by Judy and Judel Niemeyer will add a quick curve to any traditional or paper-pieced block measuring 6in or 12in in width and 3in or greater in length.

It features easy-to-read black and white markings and the popular Creative Grids® grip.

The ruler slides easily over the fabric until pressure is applied; then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
