I finally finished installing the baseboards and trimmed the walls and floors on the back side.
For the window treatments, I used a roll of lace. I added crown molding using bamboo skewers, which surprisingly fit over the narrow tops of the windows. However, real miniature crown molding won't fit, so my earlier suggestion still applies in that case. I also trimmed the kitchen pantry to give it a more finished look.
For the top of the roofs, I used a wooden dowel and filled in the gaps with stainable wood filler. It's important to choose stainable wood filler because not all types can be stained; some are only paintable. Using non-stainable filler on something that needs staining can ruin the finish.
I touched up all the exterior paint and added finials to the roofs. These finials were leftover from another dollhouse kit. I modified them by cutting off the legs and the top round part to make them smaller and more in scale. They add flair to the dollhouse since it didn’t come with roof trim and also cover where the dowels meet the gables.
You can use brick paper printed from your computer to cover the chimney and foundation.
