10inch bottom, 6 inch top white cake with buttercream icing covered in fondant with fondant and royal icing details. The birthday girl's mom wanted bright colors and circles, and her favorite color was blue...so I came up with this. I made a "17" topper to put on top when I got there...but dropped and broke it on the way :(. So I never got a picture with it on the cake. Oh well maybe next time!
