(see my project "Halloween costumes: STARTING THE PROJECT!" for the reason I made this and see my other projects for other progress on the costumes :D) These were fairly simple as well once we figured out how to make them. We took some old curtains and sheets (because we will be on stilts while wearing these) and sewed them into large jacket-like things with our grandma. I then took them home and re-enforced the seams with my sewing kit and that made the brown part. Then we took a sheet, attached some buttons to it and that made the white part!
