Aaaah - thanks for posting the photos. If you are planning on machine-sewing both sides of the binding to the quilt, you should attach the binding to the back of the quilt first, and then fold it over to the front so that you can lay it right on top of the 1/4" seam and sew along it. If you're planning on hand-sewing (my favorite part of all), then you should sew the binding onto the front of the quilt and fold it over to the back. It helps if after you do the initial machine sewing and before folding the binding, you take some very sharp scissors and snip away the extra batting between the two layers and take a diagonal snip from each corner.
