I sew on the back with a 3/16" seam (half way between 1/4" and 3/8" on your sewing machine plate) using a 2 1/2" strip folded in half, then top stitch with a blind hem foot, or a foot that has a center guide, moving my needle slightly to the left of the fold. It makes the top binding wider than the back, so that if your bobbin thread matches the quilting, it blends into the back and looks like part of the quilting. I always do this for utility quilts: kids and charity, to ensure durability.
