I went to the post office the other night to mail a package, and bought some stamps from the automated machine. I expected regular stamps, but got holiday stamps. Without my glasses, I couldn't really tell that they were anything other than pixelated holiday images, but it turns out that they're knitted holiday images.

From the USPS website:

For the 2007 holiday season, the U.S. Postal Service will issue Holiday Knits, four stamps featuring classic Christmas-time imagery designed and machine knitted by nationally known illustrator Nancy Stahl: There is a dignified stag; a snow-dappled evergreen tree; a perky snowman sporting a top hat; and a whimsical teddy bear.
