Is it art? Is it a car? Well, the yarn covered art car by Tim Klien is both. The clue is in the name: it is indeed a car covered by four miles of yarn.
Mike views this project as a hobby. The yarn car only took him a year, off and on. Cleverly he has used machine washable yarn so it doesn't matter if the car gets rained on - kind of handy, I guess.
There is everything you would want to know about this car in mind-numbing detail on the yarn car website, but I am happy just looking at the pictures.
