Often, I think that it's too expensive to buy nice stationary, that I should just use my old origami paper that's been laying around since that Christmas card project I undertook...I've even eyed old bill envelopes with their flashy plastic windows and thought they could use a little recycling. 'Tis true, use your old paper to brighten someone's mailbox, but if you're feeling especially generous, quirky, or just like making a good impression via USPS, buy some great hand-made stationary. These folks have experience making people smile with paper, let them do it for you. There are so many great paperists - here are just a few good finds.
