This 15-1/2in square ruler from Creative Grids is a great choice when working on larger blocks and T-Shirt Quilts.

• Easy to read black and white markings are printed in 1in grids marked in 1/8in and 1/4in increments.
• Use the black numbers printed on white dots and the 1/4in grip sides to cut whole inches.
• Use the Turn-a-Round feature to cut 1/2in increments by following the white numbers on black dots and 1/2in grip sides.
• The 1/4in dashed lines that are printed on two adjoining sides, aid in trimming seam allowances.
• White horizontal and vertical lines are printed on the square to show the center of the ruler. Use these lines to square up blocks based on four-patches, embroidered, and appliques
