I have a client that wants a sheet cake for father's day, half chocolate and half vanilla. The dilema is they want chocolate icing on the chocolate and vanilla icing on the vanilla side on one cake. I have been wrecking my brain trying to figure out a design that I can do and give them what they want. I am not a professional so any ideas would be great. PLEASE HELP ME!!!

Is he a golfer?  Could make a "green" on it and use the divider line as part of the golf course.

You could make a gumpaste plaque to place in the center, covering most of the seam, then place some smaller decorations above and below.

Make a tie out of fondant, place it in the center, then write the message on either side.

Hope that gives you some ideas.

i only know that they all like to drink alcohol. Maybe i can do some rum bottles and other items. great idea

This isn't the most family oriented idea, but any picture can be dark at the bottom and light at the top.
