Thanks! I used polymer clay, jewelry wire, small plastic beads (for the red lights on her side), hot glue, and string. And to clip her to my hair, barrettes. This was all under 15 bucks at Hobby Lobby. However, a lot of it was lying around my home, so that's just an estimate. At Hobby Lobby, a pack of polymer clay is a dollar (3 packs, so 3 dollars), the round of jewelry wire was about 3 dollars, the small plastic beads should be around 2 dollars (the cheap ones, not the fancy ones), a spool of string should be around 3 or 4 dollars, and any type of glue lying around your house should do for extra securing and such. So...about 11 or 12 dollars at the least. Prices probably vary from area to area, but a lot of that stuff can be found around the house where I live.
