Here’s Iron Fold Crease 3. Crease stands for Mark. Like Mark 2, Mark 42, etc. The instructions only show you how to fold Mark 3. You can make your own tweeks to make other suits. The only two you can’t make by using my instrux are Iron Patriot and the Hulk Bulster aka Egor. The shield is made out of light poster board which is almost like paper. Then I put tin foil on top. I then put tape on the back so it won’t come off.
