The topper wasn't hello kitty's full face so hubby had the idea to make it look like she was looking out from under the flowers. Flowers royal icing, buttercream on chocolate cake. I made the cakes & put half the flowers on the top cake, transported both on a plane from FL to Boston. We surprised my sister for her b-day (she didn't know we were coming), stacked the cakes, put hello kitty on, put more flowers, bead border, etc all in the backseat of a car. She was surprised when we arrived at restaurant.
