NPR is hosting a T-shirt Design Challenge this August with the popular crowdsourcing vendor Threadless, inviting listeners and the global Threadless community to submit and/or score designs based on the theme "My Sound World."

This Threadless "Causes" project engages listeners,  encourages creativity, and promotes the public radio brand in a popular space. It's also an opportunity for users and visitors to the Design Challenge page on to donate to their favorite public radio station.
