As amazing as the 2012 Olympic Closing Ceremony is (I'm watching it as I type this), I can't get the amazing images of the Opening Ceremony out of my head, namely the doves riding bicycles (dove releases have been a part of the Opening Ceremony since the end of World War I). I don't dare try to pipe a bicycle, but I can attempt a dove. You'll need stiff consistency white royal icing, parchment paper squares, a glue stick, a flower nail, a Styrofoam block to rest the nail in, a dusting pouch filled with a 50/50 mix of cornstarch and powdered sugar, round tips #12 and #8, petal tip #101, and a black AmeriColor Gourmet Writer. Start by sticking a parchment square to the nail with a dab from the glue stick.
After the head has firmed up, add dots for eyes with a food-safe marker like an AmeriColor Gourmet Writer. Not a bad generic little bird; you could pipe it in any color if you wanted something more vibrant than doves!
