Years ago I bought a 8 1/2" X 11" red laminated card called "Quilter's Strip Ticket". I use this every time I make binding. On one side it gives easy directions for cutting bias binding using tube construction. You begin with a square, which can be pieced if you need to. The other side gives charts for different widths of binding made from different sizes of squares to make specific lengths of bias binding. My Quilter's Strip Ticket was by Lamb Art Press, Inc., P.O. Box 38, Parsons, TN 38363, copyright 1985.
