The base of this cake (wilton wonder mold ontop of 8" round) was covered in MMF, Hello Kitty's head is BC (wilton ball mold, carved into an oval), all accents are in MMF. This cake was a challenge -- I originally had her face covered in MMF, but couldn't get it nice and smooth on the bottom. So off came the MMF and I used the BC instead. Thanks for the inspiring photos from other cakecentral bakers!
