For us, floors have meant unending work and choices, and more work and then more choices. Buying a house that was built in 1880 by poor mill workers, we expected to find that past owners had cut corners and gotten by with the cheapest solutions. The floors show that like nothing else!
Take the upstairs. We had a linoleum "rug" in the guest room:
We had thin strips of it all over, which I found so homey and unique. No one else I know has a floor like this! The upstairs rooms, however, had another feature that I didn't find charming. Sewing needles are stuck between all the floorboards! Perhaps these are from times when most clothing was handmade and mended.
Now, let's go further into the upstairs. How about these floors? Aren't you jealous?!
Before we fixed that problem, we needed to have a lead abatement. Our lead-covered floors had to be hidden, so we now have laminate floors all through the house. The gray paint is hibernating, as well as the splotches and newspaper and black, dirt-specked floor! Maybe someone will someday peel away the laminate and see it all again.
