This 8 inch by 24 inch Itty-Bitty Eights Rectangle Ruler designed by Lisa Bongean of Primitive Gatherings features easy to read 1/8in markings. The black and white dashed eighth inch markings show on both light and dark fabrics. The dashed 1in grid lines ensure accuracy when cutting pieces for miniature quilts. Refer to the black diamonds when cutting 1/8in units; the white diamonds when cutting 1/4in units. The ruler slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
