Mostly it was a light cotton-polyester blend. The lining on the inside was broadcloth, and the silver glyphs on the scarf were a thin satin. The dark pyramids were 100 percent cotton, and the front of the hood was stiffened with interfacing. The black material escapes me, lol, it was some thin stretchy stuff. During and after we made the costume, we realized we could have made better choices for materials, mainly using a thicker material for the yellow, duck cloth, for instance. It turned out OK, but we sure learned a lot on how to make it better.
