I would guess that most people keep their garages undecorated, or just in general do not value its aesthetic appearance very highly. I, however, keep my garage fairly clean and I find that it is nice to be greeted upon entry to one's home with at least a little bit of decoration instead of just depressing concrete. How do you decorate your garage? I have hanging at the bottom of the stairs to my garage an oil painting given to me by an acquaintance. It is a very amateur piece of abstract art that supposedly depicts a burning angel. Certainly no Van Gogh, but it's passable. A cool idea might be to paint an entire wall with a mural. I have a few friends that are grafitti artists and I might ask them to do a little something for me.
