My daughter saw an illusion costume online with a head on a platter and came up with this Homemade Head In A Jar Costume idea. To construct we took a old back pack and went to local hardware store and bought PVC pipe, elbows, and T-fittings to construct frame coming out of backpack. Just used cable ties to hold to backpack. On the top piece of pipe, I used proper size butter container wrapped in a darker masking tape, cut two holes in the sides and slid on the top piece of PVC pipe for the neck.
Arms were an old pair of kids panty hose stuffed with plastic grocery bags (very light weight) for the arms. Latex gloves stuffed with paper towels then taped onto stuffed arms. Bought long oversized lab coat and scrubs that pulled up almost to chest and she tucked her arms in scrubs, this was easy with drawstring on scrubs. Cut back and almost all of bottom of Pretzal tub, sewed it to jacket with fishing line.
Blood was made with using Blue Laundry Detergent (Liquid Tide with Downy) and Red Koolaid (heard making blood with detergent prevents from staining). Once put on, used cable ties to attach hands in place to Jar. Only hitch was, it was cold outside when she went trick or treating and Jar tended to fog up. She one "best costume at her schools contest" and received hundreds of compliments at all other events attended.
First with the headless man costume. I made the head out of paper mache, about 6 coats of paper. When it was dry I made ears and a nose out if paper then I painted it a peach colour. I then drew on the mouth and eyes and for the hair I used a light brown wool and stuck it around the back of the head. I then used a old large white shirt and cut zig zags on the collar. I painted it red to make it look like blood. I put the red all over the shirt too. I made a brooch out of cardboard to hold the collar up.
To make the shirt stand on the head I used a wire coat hanger and sponges. I stuffed inside the collar with paper to hold it. I then stuck the sponges to the wire hanger. I got tape and taped the hanger in the inside of the shirt to make it lean on the head then I placed it on the head so I could see where to cut the eyes out. For the bottoms I used old black trousers and a blue scarf. I tied the scarf around the top of the trousers and used black boots.
