Creative Grids Ruler 8 1/2" X 18 1/2"

This 8-1/2" x 18-1/2" rectangle ruler is a workhorse. It is the perfect size to span the most popular size of rotary cutting mats. And, since it is 25% smaller than the original 24-1/2" version, it is easier to manipulate. The wide width makes it the perfect choice to square up corners and borders. It features easy-to-read black and white markings printed in 1" grids marked in 1/8" and 1/4" increments. Use the black numbers (printed on white dots) and the 1/4" grip sides to cut whole inches, while the white numbers (printed on black dots) and the 1/2" grip sides add the 1/2" seam allowance. 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 miss-cuts! Use the white 45º angle to trim half-square triangles in whole inch increments. Use the black 45º angle to trim half-square triangles in half inch increments. An additional black 45º line is placed so that two angles cross 1/4" away from the outside edge. Use these markings to square up flying geese units; squares set on point or mark cross-hatching. The ruler also features a 30º- 60º angle. White horizontal and vertical lines are printed on the rectangle so the center of the ruler is easily distinguishable. Use these lines to fussy cut stripes and borders.
