Creative Grids Quilt Ruler 7-1/2in Square - CGR7

The best sewing and quilting rulers! They are marked in black and white for light or dark fabrics. They also have slightly rough spots to keep them from skidding when you apply pressure/cut. Dont worry, the spots are not abrasive to fabric, they just grip.

It is Great for quilting

No slipping. My favorite ruler brand.
