I basically do the same as Raggiemom, except that I turn it over to the back and stitch ON THE RIGHT SIDE just as close as you possible can to the binding. It's stitchine in the ditch. I usually cut my binding a little wider to give a little extra width on he back so that the stitching is sure to catch the binding. If your seam can be trimmed a smidging, do so and the binding will wrap far enough for you to catch it. I've done this several times. Makes a very sturdy binding. Good luck!
Oops! I see that someone had the same idea. I was too long in typing.
