I make my own binding. Cut strips by wof x 2 1/2". Iron in half. Sew right sides together on the front of your quilt. Hand sew the other side to the back of your quilt. If you watch the following you-tube video it shows how to do the corners really easily! I have never had a puckered binding. Good luck!
