Oh yeah! This is the kinda thing that's right my alley. Your rug looks really cool!
Right after graduating college a few years ago, I lived in a older house with cool wooden floors. "Cool" in that they looked cool ... and also felt cool all the time.
I got tired of waking up and having to walk across the cold floor with my bare feet ... but I was too broke for a rug. All the awesome looking rugs I liked were way too pricey.
Well, in school, I was influenced by what I call the "Lowe's Aesthetic" ... or "Hardware Chic" might be a nicer way to put it.
So...
I found this old dumpy hardware store in town that had all kinds of oddball stuff. (Always smelled funny in there too ... haha) Anyway, they had a pile of carpet squares like you found, plus they also had a pile of high-traffic "industrial" style carpet squares in all kind of weird colors/patterns.
They measured 19" square (well, roughly ... they're all off just a bit) and they cost $1.18 a piece.
It was like eye candy to me. They were so ugly, but super cool when I put them together. I was so excited, I purposely hid all the cool ones on the bottom of the pile until I had enough money to buy them.
I finally bought them, and they worked out well. I was too broke to buy tape, so I just layed them on the wood floors with some of that rubberized shelf lining stuff you can get at the Dollar Tree underneath. They worked awesome and I always loved how they looked.
Now I'm married and we live in a small apartment with "blah" carpet ... so there's just not quite enough room to put them out, plus they clash with the carpet, so I keep them waiting in the closet, hopefully to use in a future house sometime. I took some pics of a few of them laid out real quick to show you what they look like ... so hopefully they show up.
