i made a bust of my head for under $20 i went to micheals arts and craft and bought a big roll of plaster wrap (you can print a 40% off coupon off and use it once per visit) then went to walmart and got a couple of cans of spray foam and i had a big wooden dowel or pvc pipe and first i get a friend (one you trust lol) and i put plastic wrap over my hair and smeared vasiline on my face and neck and had my wife cut up the plaster wrap in 3-5 inch strips and put it over the front of my face then i had her put a little piece of plastic wrap over the edge of that plaster pieces then had her do the back let it set then had her pull the two pieces off i coated the inside with vasiline and taped the two pieces together and started putting the spray foam in with the dowel in it as strait as possible and if the foam starts to come up over the top you can squirt water on it but not to much let dry and there ya go i use mine all the time the first time i did was to make a tuskan raider i made mine out of cardboard paper mache and some old carhartte bibs and pvc and i think the whole thing cost me less than about $40 to make and its 501st approved so good luck to you
