I made two cakes for the ever-popular cake walk. Man, what kids will endure for a free cake!
I just didn't have the energy to create a Whoville cake, so went with a peppermint candy design instead. I traced my 8" cake pan onto paper and drew out the swirly design. Then I cut a template out of a plastic page-protector sleeve (the kind you put in a 3-ring binder) with an x-acto knife and laid it on top of the iced cake. Sprinkled red sugar over the cut out part and then carefully peeled back the template (some icing repair was required in places). There was red sugar all over the kitchen, but it swept up well!
I was tempted to flavour the butter cream icing with peppermint extract, but was advised that "kids think that's gross", so just went with vanilla.
