The state flower of Indiana is the peony (prior to 1957 it had a few others). Peonies come in many varieties, but no particular one has been designated "official." They are large, showy flowers; I'm afraid their grandeur is challenging to depict accurately in icing, but I gave it a try. You'll need stiff consistency royal icing in white, pink, red, or yellow (pretty much almost any color you have lying around), a flower nail, parchment paper squares, a Styrofoam block to rest the nail in, and round tip #12, chrysanthemum tip #80, and petal tip #101. Start by sticking a parchment square to the flower nail with a dab from the glue stick.
