This double duty 45 degree Spider Web ruler creates a variety of blocks using 3 to 10 inch strips or strata widths. Once you have cut the triangles, reposition the ruler to cut the background kite and/or corner shapes. Depending on the positioning of the light and dark fabrics, the finished blocks resemble a spider web or a four-pointed star. The ruler slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts! It comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration. Total Size - 9-1/2in x 11-1/2in
