Yes, that's real vinyl flooring.
I used free carpet samples from a flooring store.
This room even has chair rail.
Here are some pictures of the build. A lot of time was spend sanding the very rough 2x2s I had on hand. I wanted to make sure this thing was splinter free.
This is after the first coat of shellac. I did this first coat by hand.
Finishing by hand took way too long so I used my sprayer. The frame of this house has about 5 coats of shellac. The final 4 took less time than the first one I did by hand.
More pink and some baby blue.
The checkered floor is my favorite part.
