Dotty's right... cut your binding on the straight of grain, fold in half, and sew it 1/4" from the edge. there's been discussion here that you don't even have to press it in half with the iron. for speed, you can sew it to the back and use a decorative stitch to sew it to the front. i cut mine 2 1/4", but to be sure to cover the original 1/4" stitch line, you might want to cut the original 2 1/2 or more. good luck.
