These 1-1/2 inch wide rectangle rulers feature 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! These 1-1/2 inch width rulers are available in 6-1/2 inch and 12-1/2 inch lengths.
