Summary: Back in May, we announced on the podcast that we'd be making a Planet Money t-shirt. Then we got swamped in the details. This week, though, we're back with two podcasts on the t-shirt project. Today, we look at the economics of design. And we explain why ripping off other people's fashion ideas is a good -- and, for the moment, perfectly legal -- strategy for us to pursue. Music: Avett Brothers' "Kick Drum Heart"
