This 1-1/2 inch x 12-1/2 inch rectangle ruler features easy-to-read black and white markings printed in 1 inch grids marked in 1/8 and 1/4 inch increments. Use the easy-to-read numbers and 1/4 inch grip side to cut whole inches and trim seam allowances. 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! This 1-1/2 inch width is also available in a 6-1/2 inch length (Item CGR1565).
