My sister is making these to raise money to put her son through college... so, take a look, and if you'd like to buy, it goes to a good cause. Heavens knows I post enough artists that I'm not related too...

My sister makes these from white birch bark... this has a 32" wingspan, and all her art pieces are on http://naturesincarnations.tumblr.com/ 

Contact her at nicmac6999@gmail.com if you are interested in buying. She does a superb packaging job too.
