Now that the interior of the bedroom and living rooms are done, I can install the tower walls. Do not install the interior walls that go into the third floor, just install the three exterior walls for now. Use masking tape to support the top of the three walls so they dry correctly.
After the walls dried, I applied the wallpaper to the tower. This tower proved to be slightly more difficult to wallpaper than the kitchen bay so I used the same tactic for wallpapering that I did for the Beacon Hill Dollhouse bays. I cut the wallpaper at the window sills and applied the bottom half first and then the top. You can see details of how this is done by viewing my Dollhouse Wallpapering Guide
