Beheaded Boy Jar Head Costume

Hello my son is wearing this costume of the headed boy which he came up with on his on while searching the internet. I started by putting on a old longs levee shirt and ducting over it on myself then cut straight up the back and pulled off. I then taped the back back together and stuffed with plastic bags I then took a old book bag also stuffed with bag and sewed the duct tape form to it. Then stuffed plastic gloves with cotton balls and bags and ducted tape to form. I then took prepasted paper mache strips and covered the neck and chest area, after dried I painted to give the flesh color and severed look. I then took an old trench coat and put on form cutting out the pockets for arm holes when needed. I then took a cheese ball jar cut out the bottom and a half circle in the back also drilled holes for breathing and attached to the stuffed rubber gloves with double faced tape.
