When I saw these cupcakes, I nearly kicked myself: why didn't I think of that?! So here's an early preview (of the sort of thing that gets shared in the witchs' brew section of the online tour) to get your creative juices running: remember it doesn't have to be complicated to be brilliant! Jack Skellington cupcakes, simply gorgeous and oh so elegant! From http://www.kempenfeltcakes.com/Cupcakes.html "The Nightmare Before Christmas" is an obvious favorite of mine, how about you?
Also another idea: any animal cookie becomes a Hallowe'en treat by icing on the animal's skeleton! Brilliant! (The idea is from http://family.go.com/disney/pkg-disney-recipes/)
