This 5 X15 inch Itty Bitty Eights Rectangle Ruler designed by Lisa Bongean of Primitive Gatherings features easy to read 1/8 inch markings. The black and white dashed eighth inch markings show on both light and dark fabrics. The dashed 1 inch grid lines ensure accuracy when cutting pieces for minature quilts. Refer to the black diamonds when cutting 1/8 inch units; the white diamonds when cutting 1/4 inch units. The ruler slides easily over the fabric until pressure is applied. Then, the exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
