I have been asked to do a three tier wedding cake, similer to the one I have made for my daughters wedding.
The lady wants a three tier in white fondant and all the wording and everything that is pink on my daughters cake to be black, including the roses in the hearts.

The thing that I am worried about is she wants black and white carnations for a cake topper. Do you think carnations will go with the roses that are in the hearts. I am not sure as I have only been cake decorating for 7 months, and have had no training so I am worried about how the cake will look. I know that is what the lady wants, but this is my first ever order and I don't want it to look odd and people to give bad comments on the design.

Also could I have some advice on what to charge, I have no idea.
I was wondering to look up local cake decorators and ask them what they would charge. Pretending it was me wanting the cake to be made, but I feel a bit mean doing it that way.
The cake is 12inch fruit cake. 10inch sponge and a 8inch sponge.
I would appriciate any advice please.
