Base cake is buttercream covered with fondant star/spaceship cutouts. Bottom boarder is silver florist wire wrapped around a dowel to give it that spring look. Since client did not want to have/eat rice crispie sun/planets, we opted for syrofoam balls to make a very light-weighing solar system. Sun is a large styro ball covered in spatula strokes of different colors of buttercream. Planets are supported with black dowels and covered in fondant. Saturn has a styrofoam-board ring that was cut, fondant-covered, and attached to planet, and Uranus has more silver florist wire encircling it for a light ring. Planets were then hand-painted with details and colors to give a realistic look.
