Monster High Cake

I made this cake for friend's daughter a few weeks ago.  I spent hours making the colorflow decoration on top. I thought it would be easy to make, but I was wrong, lol.  The image was transferred to a piece of wax paper, outlined with thick colorflow icing, and then filled in with thin colorflow icing.  Because I worried about the black background icing bleeding through the decoration, I used mini marshmallows to prop it up.  One big lesson I learned, you CANNOT use hot water to smooth colored icing for the background of a cake.  It streaks the color and gives it a marbleized look.  That's a good thing to know for future reference.
