This multi-sized ruler features two triangles in one. Use the 45 degree side to cut half-square triangles from strips up to 5-1/2 inches wide, creating half-square triangles up to a finished size of 5 inches. Use the 90 degree side to cut quarter triangles that finish up to a 5 inch finished quarter-square triangle. The math required to cut these angles is incorporated into the easy to read black and white markings.

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.
