Now that the shell is completely dry, I need to finish the interior.
I'll start with the stucco on the first-floor ceiling because I can't do it later without ruining the wallpaper. To make the stucco, I need a small container and a thick bristle brush. I add about two heaping tablespoons of spackle to the container and mix it with one tablespoon of acrylic white paint. You can use any paint you like, but I prefer this one. The key is to have more spackle than paint in the mixture, and since the dollhouse is small, I don’t need a large batch. I mix the spackle and paint until it resembles thick cake icing. If it's too runny, it won't hold patterns and will just apply flat like paint. A thicker mixture gives more texture.
I then brush it onto the ceiling in circular motions to create a pattern. You can choose any design you like; the technique depends on how you use the brush. You can dab it, make circles, or create irregular strokes—just ensure you cover the entire ceiling evenly, including corners and edges. I applied about three coats of this mixture. It’s fine if some gets on the walls since I'll wallpaper the top half later. This mixture works well for any stucco work, even on the outside of the dollhouse, and it effectively hides gaps. White paint and spackle are always handy when building dollhouses, making this an economical choice. You'll be surprised at how quickly it dries while maintaining its texture.
Next, I’ll prime the downstairs walls, focusing only on the top half since the bottom will be covered with skinny sticks for beadboard. I primed the dollhouse upside down to avoid drips on the floors, which I plan to stain later. I need to let everything dry completely before I start wallpapering the top half of the walls. Additionally, I must wait for the stucco to dry fully before touching up any areas.
