This Homemade Batman Scarecrow Costume is really easy to make. I just bought this material and it didn’t even cost me over ten dollars. I don’t remember the name of the fabric used for the mask but it was really cheap. I just cut the eyes and used thread to create the pattern imitating the same from the Batman Begins movie. The straight jacket took me a little bit more of time. I got the belts from old backpacks.
