Creative Grids Ruler | 4.5"x8.5"

This 4-1/2 x 8-1/2 inch rectangle ruler 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. Use the white 45 degree angle to trim half-square triangles in whole inch increments. Use the black 45 degree angle to trim half-square triangles in half inch increments. An additional black 45 degree line is placed so that two angles cross 1/4 inch 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 30degree/60degree 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.
