Cut and trim without constantly repositioning your work using the OMNIGRID 360° rotating cutting mat, ideal for sewing rooms and retreats. The mat is 8 in diameter (20.3 cm) with centering guides, 1/2 in grid lines, and marked angles to support common piecing and bias cuts. Set the non-slip base on a flat table, rotate the mat with your fingertips, and keep blades sharp by cutting in varied areas.
