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.
