I was asked by Tim's work to create 300 Mardi Gras cupcakes (75 for each of their 4 divisions). The cakes were also king cake-like: there were babies hidden inside some of them and if you got one with a baby, you won a prize.
These were my decorations:
Liners
Fleur de lis
Masks
Beads, that didnt totally turn out this way.
Jester hats
All the masks
Final cupcakes:
