I saw a reference to this exhibit at the Smithsonian's American Art Museum (http://americanart.si.edu/exhibitions/online/birds/ ) this morning on the NPR website.  They had a picture of a lovely crocheted pigeon on the page, so I dug a little deeper and found the artist who had made this, Laurel Roth Hope.  Here is a link to the Smithsonian's page on her: http://americanart.si.edu/exhibitions/online/birds/artists/roth/ .  She has several Crocheted birds there and I think they are gorgeous and perhaps at times even lacy.  Enjoy!
