Ceiling Paper
Once the partitions are in and the dollhouse ceilings and walls are primed, you can add ceiling paper, if you want. The staircase of this dollhouse, goes right into the staircase opening and not over the ceiling, so applying ceiling paper before the staircase is installed will not interfere with its placement.
Because of the smooth wood, applying ceiling paper is not a requirement for these dollhouses. They take paint very well.
I had some leftover ceiling paper from other projects though, so I decided to use it on this dollhouse. I did not have enough for the kitchen, so I decided to make a tin ceiling for the Critters instead. I painted the ceiling with metallic silver paint. I will apply moldings to it later or maybe I can find something else to cover it with.
Sometimes when your assembling and finishing dollhouses, you will encounter these kinds of unexpected issues. You will have to work through them and always have an alternative ready, in case one idea doesn't work.
These are very simple, square rooms, so you can place your ceiling paper directly on the ceilings, crease along the wall and back floor edge and then cut it to size.
Apply the ceiling paper with regular tacky glue. Just use it sparingly. The paper may wrinkle a little at first but it straightens out pretty well once dry. Using tacky glue for this will help you save the more expensive wallpaper paste for your wallpaper. Ceilings are usually pretty large areas to cover and they can use up your wallpaper paste quickly. The ceiling paper is thick enough to not be affected by the moisture of the tacky glue.
The edges along the walls, do not have to be perfect because they will be hidden with ceiling trim. Cut the staircase opening with a craft knife, once the paper is dry. The same goes for the back edges of the floors.
