Use the Angle Finder to create perfect mitered bindings on corners with angles of 60, 90, 120 and 135 degrees. Cut bindings from strips, 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 tool slides easily over the fabric until pressure is applied. Then the gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts! Fully-illustrated step-by-step instructions are included.
