Thanks for all the tips!
BTW, the floor I am planning for is an older European train station, part of the interior of which will be shown. One section will be an old-fashioned kitchen and pantry area, and I'm unsure if said floor would be finished or just raw wood.
And here's a bit of trivia: I live in a Chicago bungalow which I fixed up, and in the old days, only the edges of hardwood floors were stained and painted because the center was expected to be covered with a carpet. As you might guess, I've bought stain as part of refinishing the woodwork, so I have that on hand.
What else I intend to show depends on what furniture I can obtain or scratch.
