60-degree Triangle Ruler

This 60-degree equilateral triangle features easy-to-read black and white markings.  A 1/4-inch dashed line is printed on each side of the center vertical line so you can cut 30 degree triangles that include the seam allowance.  The ruler slikes easily over the fabric until pressure is applied.  Then, the exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts.
