This cake is a full sheet topped with a single layer 6" round for the CD Base. The icing is all BC. I'm not the most talented MF artist, so I decided I wasn't going for all eatable deco and found some awesome scrap booking 3D music things. The CD was etched with Light Scribe and says "Happy Birthday Megan & Melinda" with Music Notes as a picture background. The girls LOVED it!
