Thanks, gals. It is actually the border I want to miter, not the binding. I have several books that show the technique, but thought I saw it on TQS once. I will go through the list again when I have more time.
Ricky did it, using the Animas Quilt Binding Tool. She has it on her web site. You can also use a 90 degree angle end of a ruler. Can't remember which show it was tho.
I thought Ricky demonstrated how to do mitered corners on the borders. I've been looking through all the old episodes but can't find it. Does anyone remember? Or maybe it was on his Grand Finale video? Or was it Alex who demonstrated it? Thanks for the help.
