Designed by Deb Heatherly, the Kitty Cornered Ruler allows you to create 11 different sizes of the Kitty Cornered Block. Create two blocks with each cut! This ruler has an easy to read cutting chart right on the tool. Sizes range from 1" to 6" and every half inch in between. Built-into the Creative Grids, Kitty Cornered Ruler, are grip-strips that prevent your fabric from sliding around while you are cutting. The ruler includes illustrated step-by-step instructions and is made in the USA.
