When sewing braid on skirt, baste 1/16 or 1/8 inch beyond edge of turned hem, starting 2 inches to right of center back seam, and basting on edge of hem on right side. Carry braid 2 inches to left of center seam when finishing, lapping evenly.
If hem has been stitched at top, sew braid on by hand, but it is much stronger if sewed by machine. To stitch the latter way, open up hem, and stitch on top edge of braid.
