I made this cake for a very musical family that we know, for their son's wedding. It was designed after the Taylor 914 Guitar. Everything was edible except the strings, the wooden dowels that hold them at the tuning end, and 6 toothpicks which I used to stick the tuning keys in the sides. The bottom layer was chocolate, the top layer vanilla and I used chocolate cream cheese frosting for the "dark" areas. The mother-of-pearl inlay was a true experiement of mixing several differnt types of decorating gels and swirling the appropriate colors in with toothpicks....it took a little bit of time, lol. I carefully cut out a "pattern" out of newsprint paper to keep the dimension of the guitar correct, just making it smaller than the actual guitar.
