This 15 inch Itty Bitty Eights Square 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 miniature quilts. Refer to the black diamonds when cutting 1/8 inch strips; the white diamonds when cutting 1/4 inch increments. Forty-five degree angles are marked from corner to corner - perfect for squaring up blocks. 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! Total Size - 15in x 15in Creative Grids® products are made in the USA.
