All the floors have been wallpapered except for the attic. I plan to finish the lower floors before starting on the top.
I removed all the wallpaper from the windows, which allowed me to cover the gaps in the bays. I used spackle and a metal ruler as a putty knife. The ruler's flexibility and sharp edge are great for applying spackle. I filled all the joints of the bay walls, including where they connect to the dollhouse wall. You could use skewers if you prefer; I've used them on bays before, but I chose not to this time. Once I smoothed out all the bay gaps, I applied a second coat of paint.
While that dried, I installed the doors, which required very little sanding to fit. I also glued all the exterior door trim.
Next, I installed the bay roofs. Be sure to paint their undersides in the same color as your ceilings since they will be visible from inside the dollhouse. It's important to paint them before gluing them on, and they fit perfectly.
The instructions for this dollhouse suggest installing the windows differently than other kits. They recommend gluing the panes on the outside of the walls, but I prefer to install them on the inside instead. I glued the panes into the interior openings, ensuring they were aligned and straight. I'll add the exterior and interior trims later. You can follow the instructions if you prefer; it’s all about personal choice.
The front staircase is a bit tricky. I recommend painting all its parts before assembly. I installed it according to the instructions, but I don’t advise this method as it can be unnecessarily difficult. The instructions aim to ensure a proper fit, but if your dollhouse is assembled correctly and is straight, you should have no trouble inserting a fully assembled staircase. I suggest assembling most of the staircase away from the dollhouse—excluding the railings—and then installing it as a complete unit to save yourself some frustration.
