I started working on the main floor. I just hot glued the sticks to the piece of foam core. From the set references, it looks like they used some kind of mud on the wood flooring, I guess to blend and fill in gaps. So I made up a mud mixture made of water, spackle, leftover homemade dirt, from my l'ameu diorama, and some black/grey paint. I slathered it around. It's still wet as of now. We'll see how it looks when it dries. It's great because the figures will be able to stand better.
