I made this as a trial for my Birthday. The official one will be pink & is for a friend who's 4 year old loves Glinda. I used the 1/2 ball cake & a 6inc cake for the cake skirt. I the another 1/2 ball for the bridge like form. Cupcakes of course for the yellow brick road. All are covered in BC, I used gumpaste for the side of the bridge and the crown. My friend wants BC, I want to make another with Fondant now. Thanks to all our fellow cc'rs for all the inspiration.
