With scissors, pry plug from straps loose on bottom of flip flop and pull down slightly so you can see the hole. Poke the end of the ribbon through the hole from the top side, trim even with plug, add a tiny bit of glue at the base and pull the plug back up tightly. Let dry.
Wrap the ribbon tightly all the way along the straps, making sure the strap is completely covered.
Repeat step 1 when you reach the end of the strap to secure the ribbon firmly.
Use different color ribbons to make customized flip flops that match your whole wardrobe!
