Wedding Cake Order

I have received my first order for a wedding cake which is need for the wedding on the 1st September, this is what I have been aiming for and I hope I get many more. I have done two designs as the couple could not decide which they wanted. Although I have designed this around a three tier wedding cake, they have actually ordered a four tier one and it will comprise of a 12" fruit Cake, a 10" vanilla sponge cake, an 8" lemon sponge cake and a 6" chocolate sponge cake. I will be making the fruit cake this weekend as prior to the two weeks before the 1st of September I am actually on holiday but we are only away for the first week as I had already received the order, so I want to take my time and make this perfect. The happy couple have chosen the version where ribbon goes around the cake as opposed to over the the top.
