This easy to manipulate 5in by 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.
