If I don't hem it (self-binding) like when I back with Minkee or Fleece, I will cut my binding to 3" and sew to the back with a generous seam allowance, then fold around to the front and stitch down. I use my stitch in the ditch foot with the little metal guide next to the folded edge of the binding and the needle slightly to the right of the fold and sew it down. The guide makes a nice consistent stitch width. With the binding being 3", when I stitch it down on the front, it does not sew on the binding on the back - it misses it - and just looks like another line of quilting.
