I saw this feather mobile at Lena's sale and thought it was really lovely, but I totally forgot to ask about it. Today while I was surfing the net I found it on Etsy. It's by Caitlin Keegan, and you can find it here. Have you checked out Lena's shop for other stuff from the sale?
Here is a beautiful painting by Caitlin Keegan too. If she ever sells prints of this I will buy one right away. Her blog has many other wonderful paintings and drawings to see as well.
