I did a limited edition Earth Day shirt for I'm Organic a couple weeks ago. They're up for sale right now, so grab one! (but only if you love the Earth)
The shirts themselves are organic and Made in the USA, and they feel nice, like an American Apparel shirt. The inks are water-based and non-toxic, too.
It's a lot of fun to work on a project that doesn't take a year to hit the market!
