I take my 2 1/2 in strips and begin about 4 inches from the corner on the back side of the quilt. I lay the rght sides together and fold the binding in half and sew it 1/4 inch from edge. Then, I go all the way around the quilt rounding the corners . then turn it over and sew it to the right side of the quilt. this will not make mitered corners, but rounded corners. if you want mtered corners, then start at the top edge and leave about 1 inch overlap. CLip on each side and then , fold your corners into neat little miters.
