Today, I will show you some pictures of a few small stone walls I recently built. They are sized to fully conceal infantry for Flames of War. They would also scale well as waist high walls for 28mm models. The walls are built from cardboard bases and depron foam. With this addition, I have enough terrain to cover a single Flames of War board to a medium terrain density. Today, I will show you some pictures of a few small stone walls I recently built.
