First, arrange your flip flops into the pattern you want. I think it looks nice to alternate patterned flip flops and solid colored ones.
Glue the flip flops in an alternating pattern: one on top of the other. Refer to the picture if you need help.
Continue gluing until the flip flops form a circle. This should happen naturally, so don't panic.
Finish it off by tying a ribbon through two of the thongs and tie in a knot to hang. I also used a bright cellophane flower to hide the ribbon in the thongs.
Hang on your door, put on some steel drum music, grab a cool lemonade, and enjoy the summer!
