Use the Angle Finder to create perfect mitered bindings on corners with angles of 60; 90; 120; and 135 degrees. Cut bindings from strips – and then use this tool to cut the angles to miter each corner. Continuous binding is no longer required. Use the holes drilled 1/4 inch away from each corner to mark the beginning and end of the seam allowance on each side. 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 - 3-1/2in x 8in
