I do that all the time now as my fingers no longer cooperative doing it by hand. This is how I do it and it seems to work for me. I have included a quick picture showing the back and front of a recent runner I have done.
Cut Binding at 2.75 - Press in half
Sew binding to back of quilt at 3/8"
Fold over to front and press - I will sometimes us a glue stick to keep it in place on the top
Top stitch the top down close to the fold (The top half will be a bit longer than the back so the stitching will be about 1/8" to 1/4" away from the seam on the back.
