-Sew the ribbon to the right side of one piece of fabric.
-Sewing in the middle of the ribbon will hide too much of the ribbon once the seam is sewn.
-With the ribbon sandwiched in-between, pin the adjoining side of the seam so that right sides of the fabric are together and the machine stitches that attached the ribbon are visible.
-Sew right on top of the stitches that attached the ribbon. Press the seam open and the ribbon to one side.
