I've just begun, most of it is foam or cardboard, but as I post pictures, you'll be able to see different materials. The Mario you see is a figure I bought, so don't think I made it , anyways, so far, I have the castle, the flagpole, a river/bridge, 3 giant platforms, 1 pipe, a bush, and a cloud. Those of you who like Mario, this is the place to be!
