5",8", 10" tiers. Used buttercream, fondant, royal icing and chocolate clay. All edible with the exception of the hot wheels at the bottom. I tried alot of new techniques on this cake, and made some awful mistakes, but learned alot and over all, I am pretty pleased. I dont like airbrushed color from the wilton cans. This was for an adult who loved superheros as a kid. I added comics to the sides of the cake support just for kicks.
