I decided to finish the floors before some areas became inaccessible later. I chose Victorian tile for the first floor and parquet flooring for the rest of the house. The Victorian tile is in ½ inch scale and fits perfectly. It will be used as an inlay in the center of the room, but it needs to be positioned carefully. The tile pattern must be cut and adjusted to fit the room since the tile sheet is much larger than the floor area. It's important to ensure that the tile pattern runs consistently across the floor, which will require cutting and patching.
The simple parquet flooring was installed throughout the rest of the dollhouse. While perfection is unattainable, any imperfections will be less noticeable once the walls and partitions are in place. Laying out the floor was challenging, as I had to carefully arrange very small pieces of the tile pattern using tweezers. In the end, I was pleased with the results. I applied a coat of gloss varnish, keeping in mind how shiny it would be and any imperfections that might show before adding more coats.
The parquet flooring also posed challenges due to the dollhouse's unique layout. To maintain a consistent parquet pattern across the oddly shaped floors, cutting and patching were necessary. The parquet floors were varnished as well.
When applying varnish to paper flooring, always ensure that the glue is completely dry first. It's also a good idea to test the color fastness of your paper flooring before applying varnish.
