This easy to manipulate 5" by 15" Charming Itty Bitty Eights Ruler designed by Lisa Bongean of Primitive Gatherings is the perfect size to cut 5" charm squares quickly and easily. The dashed one inch markings increase visibility - which improves accuracy. The ruler highlights the 1/8"markings which are hard to use on traditional rulers. The black and white dashed 1/8" markings show on both light and dark fabrics and ensure accuracy when cutting pieces for miniature quilts. Refer to the black diamonds when cutting 1/8" units; the white diamonds when cutting 1/4" units.
