Ice King costume FAQ
- How do I make the Ice King's crown?
- You can easily make it using yellow craft foam. Cut out a band with three tall points, glue the ends together to fit your head, and add three red craft gems or red felt diamonds to the points.
- What color is the Ice King's skin?
- His skin is a very light, icy blue. You can achieve this look using water-activated or cream-based light blue face paint.
- Is the Ice King costume comfortable for warm weather?
- The heavy wig, beard, and robe can get warm. Opt for a lightweight polyester robe and keep a hand fan nearby if you are wearing it indoors or in warm weather.
