I think Jessica Vitkus is onto something here. A network of crafters would be a powerful thing. I know Leendalu will want to be first on her block with a campaign fundraising scrapbooking party. Hat tip: Spyderkl on Big Brass Blog
I like reading Brad DeLong for lots of reasons but Dark Wraith has the most lucid explanations of economic concepts I can imagine. Read his Pulp Economics to see what I mean. It's long and complex but that's life (if you're lucky.) It's a good investment of time 'cause when you finish you'll understand it.
