This 6 1/2" x 24 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 1/4" grip sides to cut whole inches. These 1/4" grip sides accentuate the dashed lines printed 1/4" 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 1/2" grip sides to add the 1/2" seam allowance. Our exclusive gripper holds the fabric while cutting when pressure is applied. The ruler includes 30 degree, 45 degree, and 60 degree angles. White horizontal and vertical lines are printed on the rectangle so the center of the ruler is easily distinguishable.
