ZEN ~ USA Black and white postcard

Find a postcard you think your partner will like. (Picture on the front, space to write a message on the back).

On the BACK of the card, tangle a design in, in black and white, in the message space, leaving just enough room for your name, etc. Most cards have a small space above the address section to put your swap-bot ID, if you prefer)

Address and mail it naked (no envelope)

Easy peasy.
