I am making lily of the valley and carnations to go on my parents' 50th wedding anniversary cake. All the pictures I look at have the flowers sitting flush on the cake. How can I put lily of the valley on the cake? Do I lay them flat? Do I try to stand them up? It's going to be a three tiered cake and I wanted to do the swag and have a bouquet of lily of the valley and carnation flowers at each level where the swag ends. I think it will look silly if I try to stand them up at these spots?

Any advice?

BC or fondant cake? I would use melted white chocolate to attache flowers to the side of a fondant cake, and for BC, make the flowers on a 6 inch cocktail stick, then insert them into a cake OR into a straw that has been inserted into the cake with gumpaste inside it to keep them sturdy. With this latter method, you can also wire your GP flowers instead of using cocktail sticks, as the wires are safely inside a foodsafe straw and not in contact with the edible cake.
