This thing is an awesome piece of pepakura but you have to take your time with it. Once you really get started along, it begins to fall into place all on it's own as you follow the fold directions.
You guys gotta remember that my first pepakura projects were the Mk V Armor bits and a lot of those can't get the numbers attached very well, so I mostly rely on my eyes and the check corresponding face function. I didn't leave any parts out.
