I made this cake for a friend who had just found out she'd been promoted to Master Sgt in the Air Force. Her line number was 352, which I piped into the blue field. The stripes are carved from a large sheet cake. To get the proportions right, I printed the Master Sgt stripes out on the computer and used toothpicks to mark everything out in my buttercream crumb coat. The decorations are piped buttercream using a star tip.
