I had to go to the post office yesterday and they have the new holiday stamps out...
They are called "Holiday Knits". According to the postal service's 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."
Nothing against machines, but it would've been really cool if they had been handknit.
