I read a review of Zazzle written in 2003. It was very pro-Zazzle but mentioned that the shirts are made of two layers. One layer is some weird material they can print on and the inner layer is a cotton layer designed to be comfortable on your skin. The reviewer said this wasn't noticeable but it sounds weird to me. This was in 2003, so I'm not sure if they're doing it anymore. If they are, is it as weird as it sounds?
