These rectangular rulers feature easy-to-read black and white markings printed in 1in grids marked in 1/8 and 1/4 inch increments. Use the easy-to-read, black numbers (on white dots) and the 1/4 inch grip sides to cut whole inches.
The 1/4in dashed lines printed on 2 adjoining sides aid in trimming seam allowances. Use the patented Turn-A-Round feature designated by the easy to read, numerical white numbers (on black dots) and the 1/2in grip sides to add the 1/2 inch seam allowance.
The markings on this 6-1/2 x 12-1/2 inch rectangle ruler are a mirror image of the right-handed ruler so lefties will no longer have to deal with numbers that are upside down and reversed!
