Marty's costume consisted of a jumpsuit trimmed in faux fur, complete with a tail.
The headpiece is made from ultra light foam and only weighs about 10 ounces!
I began Marty's headpiece by making a cardboard mock up and pattern. The pattern was cut out of ultra light closed cell foam and the pieces were glued together using contact cement. Hard edges were sanded down using a Dremel Moto tool, and seams were filled in with calk. The entire piece was then sprayed with 6 coats of Plastidip.
