Ack, I prefer making everything myself. It makes it more personal that way. That said, I do rely on a lot of pre-defined tools and what not to accomplish that.
Here's a logo/promo I did recently, though I might adjust it more to make it blend nicely with my website. Of course, I neglected the fact that a simple logo fits nicely on a T-shirt, though I would create one seperately for that purpose.
