Thank you to Royal Bakery and their very helpful tutorial on this cake. http://cakesdecor.com/RoyalBakery/blog/68 I used 10, 8 and 6 inch rounds. Hello Kitty is made out of rice crispy and marshmellow. Banner was tricky for me. I made it way to big and heavy for such a small area on cake. I had to make supports out of wooden rods to secure banner to and it still was heavy.
