I'm a big fan of cheap Urban Outfitters rugs. I still use the green "oriental" rug I bought from them three years ago for $35. And the best part is that if I ever get tired of the rug or it gets stained, I can toss it without a second thought.
I love this $28 zebra print rug for pretty much the same reason. You could do almost anything to it without feeling bad. Imagine it in a kitchen, bathroom or even garden for a few months. Ohhh, or thrown over an old sofa safari-style. Its bohemian cousin in brown is also great and is practically begging to be turned into an upholstered headboard.
