Here's a quick drawing of a castle idea I had. I wanted a decent castle to display my knights/Robin Hood figures with. My plan was to use foamcore or to actually design rock walls and print them out somehow. And with some minor decal changes to the inside, it would convert from Knight's Castle to Monster Castle!!
I don't have the time to build the thing, but I figured I'd share the idea with the gang in case someone got a wild hair to try it.
