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 inch 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. Use the patented Turn-A-Round feature and the 1/2 inch grip sides – to add the 1/2 inch seam allowance. 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!
