How To Do It (from Instructables user canida’s directions):
“The clever costume design begins with a $13 kid’s-play tunnel. After that, you need 6 yards of sandworm-tan fabric, mouth-pink fabric, posterboard, wire, and a large cardboard box. You will need some basic sewing skills to pull the costume off, but the end result is a wonderfully squirmy and toothy worm outfit.”
