So I decided to make a bunch of cards for my Etsy shop, and with any luck I'll start a trend. I mean, emails are so ethereal. They're there, but not really. I like a card or postcard you can look at any times. Stick it on the fridge, prop it up on your desk. I love sending postcards when I travel, and not just because it's the "retro" thing to do.
Email's great, but real mail?...can't beat it.
