This 1in x 6in rectangle ruler features easy-to-read black markings printed in 1in grids marked in 1/8in and 1/4in increments. Dashed lines are printed 1/4in away from both 6in edges to aid in trimming seam allowances. The 1/2in 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 mis-cuts!
