Omnigrip by Omnigrid features basic size rulers with a fabulous feature: non-slip backs!
Omnigrip also features a left- and right-handed numbering and angle system and transparent, neon green double-sight lines. Measurements are printed on the ruler for the squares needed to cut all side corner triangles. This is the all-purpose basic for beginning to advanced quilters. The 24" length stretches across the width of fabric as unfolded from the bolt, making it easy to cut long strips.
Includes 30, 45 and 60 degree angle markings plus 1/8" markings throughout.
