Anyway, it was fairly easy to decorate the plastic pieces - just used icing and edible glitter/colored sugar sprinkles.
Oh yeah, and this is what I look like at 2AM when I finish a cake fit for a princess. It didn't really have to keep me up that late, but I am a night owl by nature. I just should have baked the cakes and gotten the castle supplies the day before. Then I could have gotten to the decorating earlier in the day and gone to bed before midnight. The cake actually only took about 3 hours to decorate once I got going on it.
I just hope nothing happens to it when I deliver it! (It's on the same street, several houses down from mine.) Just pray that I don't have a "cake-tastrophe"!! Sorry for the weird lighting issues on the pictures - I don't know what's up with my camera.
