Last step of construction! I used a silky white fabric for the eyes, though anything white will do. Use a black mesh for the pupil, the darker it is the lower your visibility will be. Cut out two ovular or arched areas above the nose, symmetrical if at all possible. Cut out whatever shape you want the pupil to be in the white fabric you use for your eyes, and glue or sew your pupil material on the side of that hole that will be inside the costume. Finish by gluing your eye/pupil assembly to the inside of the holes on the outside of the costume.
