Not to be outdone by Artevist and Green Eyed Monster, Threadless — a website that crowdsources T-shirt designs, is having its own green contest in preparation for Earth Day on April 22.


The contest, dubbed Threadless Loves Green, challenges you “to create a design based on the concept of thinking GREEN!” Yes, the topic’s broad enough that you can base your design on pretty much any green topic close to your heart.


The winning design will get printed on organic cotton T-shirts — and the designer will get $2000 in cash, $500 ini Threadless gift certificates, green prizes includinga Timbuk2 Hacker Daypack bag and Origins Organic products — plus other less green-related prizes like a digital painting AND a detailed portrait of yourself, an original song about a topic of your choosing, and much more.


So get designing and send your best work in by April 6! You can submit up to 3 designs, to be judged by Threadless staff and sponsors.
