Cut the ribbon into four even pieces.
Pick up one toe shoe and identify one of the side seams. Measure 1/2-inch back toward the heel from the seam and mark the spot on the inside of the shoe with a pencil. Repeat on the other shoe.
Using small stitches, sew one piece of ribbon to one side. Place the ribbon shiny side-down over the pencil marking and sew with the matte side facing you. Repeat on the other shoe. Finish by trimming the free end of the ribbon at a 45-degree angle.
Repeat Steps 2 and 3 for the other shoe.
Cut the piece of elastic into two even pieces.
Sew one end of one piece of elastic to one side of the seam down the middle of the heel of the shoe.
Put the shoe on and wrap the elastic around your ankle. Determine the length needed to make the elastic snug but not overly tight. Trim the elastic to this length.
Sew the other end of the elastic to the other side of the seam down the middle of the heel of the shoe.
Repeat Steps 2 to 4 for the other shoe.
