In the spirit of an etsy postcard trade i'm featuring this superawesome fabric QUILTED postcard from Lucy's Postcard Quilts. These are FABRIC postcards that you can really send in the mail! Granted, you have to use a fabric pen to write them out and it MIGHT be a good idea to practice a little first, but they're so cool who cares, right? (I asked her about stamps sticking to the fabric- the stamps stick and they STAY so no worries about that- they also cost a little more to send than your average postcard but at 39cent stamp ought to do it)
Some of my other favorites from Lucy are kitty postcards. But she has tons of other fun things, all quilted, all mailable, and all supercool.
