The Omnigrid double-sided cutting mat is the largest double-sided cutting mat in the Omnigrid collection - its large size makes it suitable for cutting borders and bias strips; it's also convenient for measuring fabric by the yard and it can accommodate a standard folded width of 45-inch fabric. Features 1-inch grid, and 1/8-inch edge markings and angle line markings on one side for measuring and cutting; the opposite side is metric, with a centimeter grid, millimeter edge markings and angle line marking. Couple your Omnigrid mat with an Omnigrid ruler for ultimate measuring and cutting accuracy. Use with a rotary cutter or a straight-edge blade.Details:Green24" x 36"1" grid with 1/8" edge markingsMetric grid on opposite sidePair with Omingrid ruler for best accuracyPlastic
