Silhouettes.

I love 'em. We had flower silhouettes I painted in our last place, and I have the new one in the living room. Today, via the blog Laissezfaire, I found the Web site Vinyl Silhouettes. Some of their examples are really neat. I would argue you don't need to pay someone else--if its a simple shape, silhouettes aren't that hard. And if you have an overhead projector, it's even easier. Just turn a printed photo into a transparency and trace it. That is what I use. Best $10 I ever spent on Craigslist.
