This 12" Wave Ruler designed by Judy and Judel Niemeyer will add a quick curve to any traditional or paper-pieced block measuring 6" or 12" in width and 3½" or greater in length. Compatible with the Quiltworx Charm Elements, it will create a variety of layout options!

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!
