Mauve and White Fondant over Buttercream. Ribbon Roses and Fondant Bow. This cake was made in a little over an hour and a half. This was my first attempt at a fondant bow and I didn't have enough time to let it dry completely (so it drooped on one side). All in all it turned out well. If I'd had more time to be creative, I would probably added a brim to make it look like a hat.
