Ribbed siding

I finished the exterior not only to make the room more attractive on a shelf but to add thickness and stability to the base kit wood. I bought this siding some time back and it wasn't exactly what I wanted for that project. I kept it in my stash, and today it came in handy without my having to buy additional materials. For the sides, I followed the guidelines. For the back, I left some overhang to overlap the sides.
