This 1 inch x 6 inch rectangle ruler features easy to read black markings printed in 1 inch grids marked in 1/8 inch and 1/4 inch increments. Dashed lines are printed 1/4 inch away from both 6 inch edges to aid in trimming seam allowances. The 1/2 inch line is clearly defined through the center of the ruler. 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.
