When we were kids, we really liked the whole idea of traffic signs as art.
We dreamed of having a STOP sign up on the wall in our bedroom (heck, we would've settled for YIELD). So, we really like these coasters by artist Boris Bally. However, they're a little pricey, and cost much more than we paid for our coasters.
These DOT coasters will put you back at least $65 for a set of 4.
But, in some ways, they are like art for your coffee table. And they seem like a pretty cool way to reuse old metal traffic signs, especially if you're into that sort of thing but don't feel like hanging "NO U-TURN" above your bed.
