I started by trimming the bathroom and kitchen. Adding ceiling and floor trim significantly enhances the finished look of a dollhouse. I used the same size trim for both the floor and ceilings. Since the kitchen wallpaper has a border, I applied the ceiling trim directly against the ceiling instead of on the walls to avoid disrupting the border design.
The ceiling paper in the bay area was already in place, so I added wallpaper to the exterior edge of the bay opening. This edge will be visible through the bay windows when looking inside, so I chose to wallpaper it rather than paint it.
Next, I installed the kitchen bay walls. I had to adjust my approach here. There are two methods for wallpapering these walls - before or after installation. Following the original instructions would require wallpapering each wall individually before installation, which would leave gaps on the interior that need to be covered with wooden dowels or trim. Spackle is not a good option for this, as it won't blend well with the wallpaper due to the gap size. Instead, I opted to wallpaper after installation, which eliminated visible gaps.
After installing and wallpapering the walls, I placed the window seat once everything was dry. Although getting the window seat in after installing the walls can be challenging, it was worth avoiding gaps between wall joints. You might notice some damage to the edges of the bay window opening, but these can be easily repaired once the seat is in place. Be sure to finish your window seat with paint or stain before installation.
This dollhouse does not include trim for the bay or tower openings, so I made my own. I can't leave them without trim, so I added trim to the sides of the bay opening and placed wooden caps on top. I sanded, filled, and painted all edges to ensure they are smooth and gap-free. Since I couldn't bend wooden trim into an arch for the top of the openings, I used fabric instead. I glued fabric ribbon along the top of the arch and painted it once it dried, giving it an appearance similar to carved wooden trim.
Finally, I upholstered the window seat and continued applying baseboard trim throughout the room, including around the kitchen door opening. I also added wooden caps to the tops of door trims.
