Sew together twelve 30 degree triangles to create a complete circle; six to create a half-circle; or three to create a quarter-circle. Or, use the angles to create a variety of intricate 12in finished blocks - no paper templates required!

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!
