2X Magnified Artwork postcards

For this swap, you have an interesting challenge: Create a piece of artwork that is 2" by 3", then enlarge your artwork using a scanner or camera or photocopier, so that it is now 4" by 6". Then, make the enlarged copy into a postcard and send it to your partner. Subject matter is totally up to you, and ANY media are welcome, as long as you keep in mind that the goal here is to create tiny artworks that will have lots of cool textures and hidden details that will look awesome when the art is magnified to twice its original size. Creations must be your original work.

Your card must have the swap title plus your username printed clearly on the back, and you should write some sort of message to your partner on the back of the card. I hope to break people away from only including the bare minimum of required information. Surely there are interesting things to say!

The fine print:
This swap is INTERNATIONAL.
Cards must conform to standard USA postcard sizes - they must be between 3.5" by 5" and 4.25" by 6".
Must have a 4.5 or higher rating, or else contact me and explain your circumstances.
Newbies welcome with completed profiles.
