I have a teepublic site at www.podcastclothes.comwhere I have shirts for my show, but also shirts I think the podcast community would enjoy. (Note to self pick a domain that is easy to pronounce).
I've heard of podcasters who have their audience design the shirt, then they vote on it, and the top shirt then become a "one time only" run (to put a little fear of missing out into the marketing mix) and the whole communities buys the shirt (and the artist gets a piece of the action).
I bought a tapestry that came out really well and then used it for my video background (it's light material, looks great, and wasn't hard to hang as it was light).
