In Search of a Hobby

It's come to my attention that I am in serious need of a hobby. Julien is back from his floating trip and I finally have some time to myself. So I thought I would go do something. Then, I realized that I don't really have any meaningful hobbies over than shopping. So I need a hobby that will get me out of the house and away from mommy-duty. And isn't terribly expensive. (Hence the problem with my shopping hobby.) I am open to suggestions. I will not camp or do anything camping-like. But over than that, I'll consider most things. :)
