These square rulers features easy-to-read black and white markings printed in 1 inch grids marked in 1/8 inch and 1/4 inch increments.
Use the easy-to-read, black numbers (printed on white dots) and the 1/4 inch grip sides to cut whole inches. The 1/4 inch dashed lines printed on two adjoining sides aid in trimming seam allowances. The grips on the bottom of the rule engage when you press on it to cut and prevent slippage!!
