William and Kate wedding cake. Can you say O..M..G... When i first saw the cake all i thought about is how long did it take her to make it. I read somewhere it took five weeks to create this master piece. The designer of the cake is Fiona Cairns I have never heard of her before, but she has been in the business for 25 years. This cake is beautiful, the attention to details are crazy. Here is a top view of the cake. When i first saw it i started counting the tiers. LOL
