Okay, I do basically what everyone else does...however, I use a 3" strip, fold in half, press and depending on my mood I sew the raw edge side to either the front or the back using closer to 3/8" seam. I do miter my corners and usually hand stitch the other side down. I have been known to use a decorate machine stitch instead of hand sewing, especially since I have had problems with my right hand.
