Buttercream frosting, with fondant accents. "Wooden floor" was a piece of rolled and cut fondant that I striped with combos of yellow, brown and orange watered down wilton food color dye. Ball was covered in fondant that I marbalized by adding stripes of dye to fondant and then folded and pulled , then rolled out. Added a bit of silver powder with paint brush folowing the dark blue stripes after ball was covered. Bowling pins are sculpted fondant. I let them harden for several days.
