This left handed version of the 4.5" square is a mirror image of the original. Now those that cut left handed will be able to read the numbers and markings right side up. - Perfect for projects using 5" pre-cut squares - The 45 degree diagonal line makes trimming half-square triangles easy and accurate. - Easy-to-read black and white markings printed in 1 inch grids and marked in 1/4 and 1/8 inch increments. - Use the black numbers printed on white dots and the 1/4 inch grip sides to cut whole inches. - Use the patented Turn-A-Round feature to cut 1/2 inch increments by following the white numbers on black circles with the 1/2 inch grip side. - The 1/4 inch dashed lines printed on two adjoining sides aid in trimming seam allowances. - White horizontal and vertical lines are printed on the square so the center of the ruler is easily distinguishable. Use these lines to square up blocks based on four-patches, embroidered and appliqued blocks. - The ruler slides easily over the fabric until pressure is applied. Then our exclusive grip holds the fabric in place while cutting, eliminating slipping and miss-cuts. #CGR4LEFT
