I made this cake for a 2 year old's birthday. The bottom tier was a 2 layer 14" round. The top tier was a single layer, with some scraps used to supplement the contours on the Care Bear's face and cheeks. It was all covered in Rolled fondant. The clouds were made of royal icing, and attached when firm. The top tier (the Care Bear) was supported by a base of 1/8" clear plastic base - cut to the shape of the care bear, and supported with dowels into the bottom layer (assembled like a wedding cake).
