Do you have a lot of old postcards and notecards that were sent to you? Maybe you didn't like the image that much, or it's just tucked away in a box and you don't know what to do with it.

For this swap, send 1 reused postcard or notecard, sender's choice. If it had previous writing, you can cover it with a blank piece of paper, and write a new nice message to your partner, make sure it's glued very well so it arrives in one piece. If it's a notecard, you can cut it and send the part with the image. Send naked, or if you think it needs to go in an envelope, feel free to send it that way.
