Use the straight side of this triple strip ruler to cut 1-1/2; 2-1/2; and 3-1/2 inch strips or use the pre-cuts that are on the market. Sew these strips together to create a 6-1/2 inch wide strip set. Rotate the ruler to cut 120 degree triangles that finish to a height of 6 inch. Continue to rotate the ruler 180 degree to cut additional triangles without wasting fabric. The easy to read black and white markings allow you to cut 2-1/2; 4-1/2 or 6-1/2 inch triangles. A 1/4 inch dashed line is printed on each side of the center vertical line so you can cut 60 degree triangles that include the 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! The ruler comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration of these features.
