Ruler size: 8.5" square
The Square It Up and Fussy Cut Ruler is a dual purpose tool. Use the vertical, horizontal and diagonal lines to square up any pieced, appliqued, or embroidered block. To fussy cut, center a design in the solid squares - printed in 1" increments. The drilled holes at the .5" markings between the squares let you mark and add the seam allowance to your fussy cut piece. Easy to read black and white markings. Gripper holds fabric while cutting.
