This was a huge cake with alot of mistakes but i think i pulled it off. i went for a topsy turvy design. bottom layer is carved from 11,10,9 inch cake. middle layer is 8 inch and top layer is 6 inch. Guitar ,mic and piano on top is made of chocolate using molds and the rest of decorations are fondant. I do not think i will make a cake this big again. My daughter thought it was the coolest though so that is all that matters. Thanks for looking!
