No problem at all! <333 I hope they have fun. :3 Rolled fondant's kind of cool, actually, it's icing but it's more like... like clay, I suppose. You can manipulate it into shapes, roll it out into a slab form, whatever you'd like! It's a tiny bit smelly, and I don't think you're supposed to eat it. We took it off my cake before cutting it. :P

Really though, no problem. :3 I hope it works out for you! Let me/the Hetalia community in general know what you come up with for a cake? :)
