Cut an array of popular pre-cut shapes from a 5 inch square or from scraps. Or cut around the ruler to cut your own charms! The quarter inch grid covers the entire square. Popular cuts such as the two and a half, three and a half, and four and a half inch squares are highlighted. A diagonal line makes quick work of trimming half-square triangles. The ruler slides easily over the fabric until pressure is applied. Then, the exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
