ribbon or fabric to line the headband
feather pad (I got this one on etsy.com I've also seen some at Hobby Lobby)
an embellishment of your choice: large button or gem, or fabric flower (I used my Oh Sew Easy fabric flower)
All you do is glue the ribbon on the headband with hot glue or wrap and glue some fabric on. Then hot glue the feather pad and embellishment on the headband and then cut a piece of felt to glue behind to help it be more secure.
