Whether on the cutting table or the sewing machine: the Omni grid universal rulers from Prim are indispensable companions for patchwork, dressmaking and tailoring or for graphic work. The yellow and black grid markings in a metric or inch scale make it possible to mark accurately on both dark and light fabrics. The scratch-resistant laser print on the underside of the ruler prevents visual distortion. Thick, resistant, durable material guarantees safe guiding of rotary cutters and art knives on the cutting mat. Some versions of the Omni grid rulers also have 30, 45 and 60 degree angle markings for cutting out triangles, diamonds and strips on the bias. To keep things tidy, it can be hung up by its eyelet.
