hmmm. you've made me think....well his legs would have to be in black to represent the antenne. and you coudl do the black arms and white gloves for mickey...but you've got me totally stumped for the body.
wait! i've got it i think. get a hula hoop and whatever color fabric he wants for his mickeys body adn put a drawsting or velcro around his neck. two holes in the bottom, and wait im stumped again for the middle. sorry, my drugs make me kinda loopy! lol k so have the hoop in the middle, and cover it with the fabric- almost like looping it through a waist line of jeans. you'd have to make the loops inside. then it should be almost round.
hope that helps a little! i'm sure someoen can throw thier two cents in.
