Made the crown with craft foam sandwiched with worbla. the jewelry was a combination between worbla and air dry clay from Daiso! (Tried to be as cheap as possible)
Hair runes were craft foam, painted to hair color, painted the wig to match, and then glued an LED along the strip....but I should have used something to diffuse the light >_< but idk how to keep it flexible with the hair?? hmmm....I'll fix that eventually
