Be a part of the hate.
Right-- I've just created my first t-shirt with Zazzle. You can see it, and any other stuff I make, here. It is way overpriced for a naff t-shirt with some writing on, so some of you may be thinking of going out and just buying a t-shirt off the market and writing on it with a magic marker. If you do this I'll kill you with my evil magick skills. Just saying.
(Edited to say that the t-shirt no longer seems to appear in my gallery. I have no idea why, but I'm trying to fix the problem.)
