I have been nervous about this cake for awhile! Customer sent me a similar idea, but the Lakers Stadium. Wanted the United Center and Bulls. (Kinda funny...we are in Philly but doing the United Center during the HOCKEY championship, for the BULLS. ha.) The ball is styrofoam/fondant but the rest is cake and fondant. Lettering on the top is done freehand (copying a font) because I couldn't get it to transfer cleanly. Glad this is done! Serves about 60-65 (they ordered 50...oops!)
