Alright mate, if you go over to the front page of the forum, there is a sub forum dedicated entirely to tutorials. Please check that one out, and possibly look up building with pepakura with google. Punished Props is my favourite youtube series on building props, but focus mainly on foam. They do have an old video on pepakura though. Before asking too many more questions though, please go check out the links in the tutorial section, google, and consider making a new thread for any questions instead of using this one. Thanks mate, good luck.
LOVE & JETT,
Squish
