Dandy-made postcard swap

Send your partner one handmade postcard. It needs to
A) be able to go through the postal system appropriately (check size restrictions, postage requirements, etc)
B) be handmade by you
C) be creative and (in your eyes, at least!) attractive. Whether your swap partner likes it is out of your control, but your aim is to send something they will like. :)
D) contain your user name and swap info (or at LEAST user name, if somehow swap info messes it up)

You may use any method you like to decorate your card, but it should require a bit of effort on your part.

The theme of your postcard will be a surprise for your partner, chosen from your partner's profile. If you need more ideas, PM them.

This card will be mailed in an envelope, for your partner to use. The envelope will be decorated somehow to coordinate with the card. (If you would rather receive your card naked, you may request this from your partner.)
