Creative Grids Quilt Ruler 12-1/2in x 24-1/2in. This 12-1/2 x 24-1/2-inch rectangle ruler is a whopper ? it's the largest rectangle on the market. We call this one THE BIG EASY. This ruler is the perfect choice for home dec projects, trimming quilts, marking cross-hatching, and cutting borders. It features easy-to-read black and white markings printed in 1-inch grids marked in 1/8 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. Use the patented Turn-A-Round feature ? designated by the easy to read, numerical white numbers (printed on black dots) and the 1/2-inch grip sides ? to add the 1/2-inch seam allowance. As a bonus, the ruler also features a variety of angles - 30, 45, 60, and 120 degree angles - that run in opposing directions. White horizontal and vertical lines are printed on the rectangle so the center of the ruler is easily distinguishable as well. Use these lines to fussy cut stripes and borders. 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!
