This easy to manipulate 5in x 15in Charming Itty Bitty Eights Ruler designed by Lisa Bongean of Primitive Gatherings is the perfect size to cut 5in charm squares quickly and easily. The dashed one inch markings increase visibility - which improves accuracy. The ruler highlights the 1/8in markings which are hard to use on traditional rulers. The black and white dashed 1/8in markings show on both light and dark fabrics and 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 3/16in marking printed along the length of each side of the ruler are the perfect width for cutting wool bias strips for applique. One is white and one is black. Choose the line that shows best on your chosen fabric. 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! Total Size - 5in x 15in Creative Grids® products are made in the USA and sold in independent quilt shops only.
