Creative Grids Quilt Rectangular Rulers

These rectangular rulers feature easy-to-read black and white markings printed in 1in grids marked in 1/8 and 1/4 inch increments. Use the easy-to-read, black numbers (on white dots) and the 1/4 inch grip sides to cut whole inches. The 1/4in dashed lines printed on 2 adjoining sides aid in trimming seam allowances. Use the patented Turn-A-Round feature designated by the easy to read, numerical white numbers (on black dots) and the 1/2in grip sides to add the 1/2 inch seam allowance. Use the white 45deg angle to trim 1/2 square triangles in 1in increments. Use the black 45 degree angle to trim 1/2 square triangles in 1/2in increments. An additional black 45 degree line is placed so that 2 angles cross 1/4in away from the outside edge.
