The printing with yellow/black grid with measurement scale or inch allows precise indications on both dark and light fabrics. The scratch-resistant laser printing on the underside of the ruler eliminates visual distortions. The thick, durable material ensures safe guidance of rotary cutters and pull knives on the cutting mat. In some versions, Omnigrid rulers also have 30, 45, and 60-degree angle indications for cutting triangles and diamonds as well as diagonal strips. A hanging hole also ensures order in the workspace.
