This book shelf takes a lot of work. There are a lot of tiny gaps that must be filled in, along the shelf sides and back. It takes sanding between coats of paint to make a smooth finish.
I used thin strip wood for the front edges of shelf side walls. I also finished trimming the ceilings.
I applied strip wood to the back edges of the floors. The two narrow, back, side-walls are painted white on the interior, but they do not have to be wallpapered. Just make sure you do finish them properly, as they will be visible from the other side of the dollhouse.
