This 6 1/2″ x 18 1/2″ rectangle features easy-to-read black and white markings printed in 1″ grids marked in 1/8″ and 1/4″ increments. Use the easy-to-read, numerical black numbers (printed on white dots) and the ¼ inch grip sides to cut whole inches. These ¼” grip sides accentuate the dashed lines printed ¼” away from two adjoining edges to aid in trimming seam allowances. Use the patented Turn-A-Round feature – designated by the easy to read, numerical white numbers (printed on black dots) and the ½” grip sides – to add the ½” seam allowance. Our exclusive gripper holds the fabric while cutting when pressure is applied. The ruler includes 30°; 45°; and 60° angles. White horizontal and vertical lines are printed on the rectangle so the center of the ruler is easily distinguishable.
