The Creative Grids Alaska Ruler, designed by Edyta Sitar of Laundry Basket Quilts, cuts a multitude of shapes in a variety of sizes. Cut 45 degree wedges, diamonds, squares and half-square triangles all with the same ruler! The instructions include how to make a basic kaleidoscope block as well as an Alaska block in four different sizes, from 9 to 16-inches. 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!
