I've baked DD's birthday party cake every year and plan to do so this year again. I am fine on the baking part, zero on the decorating. What do I need to get to decorate her cake - or get into the decorating thing in general? I literally have no clue. Is there some kind of special squeezy tube you decorate with, and where can I find this? Special sprinkles that help with decorating? I am literally clueless and so not Martha Stewart. Help! Thanks for any suggestions on what to buy and where. Photos of your decorated cakes would be great too! DD wants either a squirrel or Tinkerbell - um, we'll see.
