Here's what we used:
100% Polyester Ribbon
Wooden dowels( I bought the 12 inch long ones in the cake section- they were prefect)
Fray check or Stop Fray
Thread and Needle
Preheat the oven to 250 degrees.
Use a clothespin to hold one end of your ribbon on the dowel and begin to wrap the ribbon. Once you reach the end of the dowel, cut the ribbon and use another clothespin to hold it in place.
Place the wrapped dowel on a baking sheet covered with aluminum foil to make sure the ribbon stays clean.
"Bake" your ribbon for about 30 minutes. Check it at about 20 minutes to make sure your ribbon is not browning.
Take the baking sheet out of the oven and allow to cool. When the ribbon is cool to touch, slowly unwind it from the dowel.
Cut the ribbon into 2 1/2- 3 1/2 -inch lengths (choose the length that looks best to you) and apply Stop Fraying to the ends. Allow the ribbon to dry. Thread the needle and knot the end. Run the needle through the center of each ribbon segment until you have the number you want threaded. For the flip flops I made two groups of 9 for each shoe. Once you have threaded all the ribbon pieces, run the needle back through and pull it tight.
Apply E-6000 to the flip flop strap and the bow. Wait a second or two until the glue becomes a little tacky. Attach bow to flip flop. I attached a bow to each side of the toe divider piece.
Use a clothespin to hold the bow in place. Allow 12- 24 hours to dry. There ya go!
