I made this for my friends 16th bday. I was trying to make it look more like a guy"s cake...it is so much easier to do girl cakes!! The piano is made out of rice crispy treats and covered in fondant. I made the keyboard out of fondant. WOW those keys were small!!! I also tried out my new airbrush on the bottom tier....awesome!!!! Except mom was cleaning up red for three days. :D
