Here is the stock of Disney barrettes I made for the girls to wear. I'd found some similar on etsy but decided to make them myself. They are fairly easy to make! You need some alligator clips, some ribbon as wide or wider than the clips, a hot glue gun, some buttons in Mickey shapes (purchased on ebay but available at JoAnn or any scrapbook store) and sme shelf liner if you want to make them non-slip.
Cut the ribbon long enough to cover the inside of the clip, pull it over the top and end and go alng the bottom and inside. Use hot glue gun to adhere the ribbon. Decide on placement of buttons and glue on. Add small scrap of shelf liner for non-slip grip with hot glue on the inside bottom of the barrette. Voila. You're done!
