I know that there are a number of websites that allow you to use your artwork to create products like t-shirts and mugs available for sale, but I didnt realise that the print on demand industry has taken off on the web as well.
Sites like Lulu.com seem to have finally made self-publishing rather easy to do, which is good news for those of you writing your own books. Of course, the bad news is now you actually have less of an excuse to never finish them.
