Someone asked me about the details of the cake:
The wedding cake, designed by Fiona Cairns, is made from 17 individual fruit cakes (12 of which form the base) and has eight tiers. The cake has been decorated with cream and white icing using the Joseph Lambeth technique. There are up to 900 individually iced flowers and leaves of 17 different varieties decorated on the cake. A garland design around the middle of the cake matches the architectural garlands decorated around the top of the Picture Gallery in Buckingham Palace, the room in which the cake will be displayed.
