Creative Grids 20 1/2x22 Square Ruler

This 50cm square features easy-to-read black and white markings printed in 2.5cm grids marked in 0.3cm and 0.6cm increments. Use the easy-to-read, numerical black numbers (printed on white dots) and the 0.6cm grip sides to cut whole inches. These 0.6cm grip sides accentuate the dashed lines printed 0.6cm away from two adjoining edges to aid in trimming seam allowances. Use the patented Turn-A-Round feature - designated by the easy to read, numerical white numbers (printed on black dots) and the 1.3cm grip sides - to add the 1.3cm seam allowance. Our exclusive gripper holds the fabric while cutting when pressure is applied. A 45 angle is printed in black. White horizontal and vertical lines are printed on the square so the centre of the ruler is easily distinguishable.
