i was asked to do a boombox cake for an 80's themed party. They want the cake to play music! I think I can get some small mp3 speakers that you connect to your iPod and run the wires through a straw and cover the speaker portion with fondant?! The cake needs to be large enough to serve 150 I have never made a cake this large that is not stacked tiers so I don't know how to cover this with fondant in one piece, any help would be much appreciated! Also, any advice fir making a gold chain? Any suggestions are welcomed and appreciated!
