Do the final waistband fitting and stitch up the waistband centre back. Once this is done, measure the belt to fit, and sew the two together at the centre back seam. Once stitched together at the centre back, fold the centre back of the belt in half lengthwise and press, and stitch the remainder into place on the waistband facing.
