I too cut mine 2.5", fold in half and sew onto the back. I bring it to the front and use Elmers school glue (water soluble) to glue it down and make sure my corners are mitered. I then use my stitch in a ditch foot and off set my needle to the right and sew the binding down. I mostly make donation quilts. I originally was taught to hand sew the binding onto the back of the quilt, but quickly learned I did not like hand sewing. I've already made 17 quilts this winter, pieced the front, quilted and binding, I would have a big pile of UFO's if I hand stitched the binding to the back.
