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 2-1/2; 3-1/2, and 4-1/2 inch squares are highlighted. A diagonal line makes quick work of trimming half-square triangles. The Perfect 10 (Item CGRPERF10) features similar markings but is designed specifically for ten inch squares.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! It comes with fully illustrated step by step instructions or view a video demonstration.Total Size – 5in x 5in
