Cake - Purple Flowers

I was asked to use the cake topper and design the cake around it.  It was a small, chocolate cake with raspberry filling (our most popular flavor) so I tried to make it as beautiful as I could.  The flowers are silk, which I prefer over real ones.  The person receiving the cake sometimes likes to save the flowers as a memory.  I also prefer silk because I don't worry about any pesticides getting into the cake and making anyone sick.  I rinse the silk flowers very well to wash off any dust that it may have collected and soap up the stems well to clean off all the "fingers" that touched it.
