Well, I have a solution to the paper floor and it's easier than you think.
If you're just a tad-bit handy, then you can make your own set of faux vintage floors on the cheap! For the 5' x 3' floor in my studio, the total cost (with blowtorch, stains, polyurethane, rags, sandpaper and wood glue) was under $50. If you already have tools/stain/glue and all you need is wood, then the cost shrinks to $15! The wood is nothing more than $2.55 cedar fence boards from a big box store. Completely assembled, the weight is 18 pounds so it's easy to move and store when not in use.
I originally was going to create a post that detailed each step but soon found myself writing a novel. Instead, I put together a 4 minute video on how to transform new-cedar into vintage-cedar using nothing more than a blowtorch, some sandpaper, and wood stains.
Once the wood is vintage-ized, then all that's left is assembling the planks side-by-side. Using scrap wood (or more cedar boards cut shorter if you want), affix the boards using wood glue and a lot of weight to hold them together. Don't touch it for a few hours so that it dries nice and solid. You can see from the photos below how I assembled my floor with the cross-braces mounted to the bottom:
I literally made this floor in an evening and that includes all the breaks I took in between. Since I was going for the worn and weathered look, there was no need to perfect anything or mull over details. The more I messed up the better it looked! I made sure each board was done a little different so there was good variation throughout the floor. For the polyurethane coat at the end, I let it dry for a week before actually using it. That stuff is stink-k-k-ky!
I hope this post helps or inspires you to try and make a wood floor from scratch. I have to admit that it's really rewarding to use something self-made during a photo session. If only my wife could learn to knit then I'd be a really happy photographer!
