I know how to measure by getting the dimensions of the center of the quilt horizontally and vertically. I can apply the binding to the horizontal sides and then to the vertical sides -- having 4 separate binding pieces. I succeed well with this method. My quilts are squared when I am done. BUT -- I would llike to apply the binding in one piece, mitering the corners. I know how to miter. What I DON"T know is this: how do I apply the binding all around without having wavy edges?
