I got this pic recently from *Kat* who made some of my NaniBirds using something called CraftRobo. It's a kind of die cutting machine for all kinds of flat materials. Using it she made tiny versions of the birdies... you can see the size comparison to the envelopes in the background. At $300 the CraftRobo is waaaaay too rich for my blood but it probably makes for some interesting and accurate results.
