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 layer cake! The ruler slides easily over the fabric until pressure is applied. 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.Then, the exclusive grippers hold the fabric in place while cutting, eliminating slipping and miss-cuts!
