Fairy Birthday Cake
This is a full sheet, (1/2 chocolate, 1/2 banana), with a whipped topping. I drew the picture by hand then traced it onto a kopykake transfer sheet with food coloring pens. Then I laid it on the cake and filled in with gels. I airbrushed it with green, because that was my co-workers favorite color, and added sprinkles for a final touch.
