i am making a cake for a good friend for her husband, she wants a 3d dog cake, grey hair, with happy birthday you old dog on it. i know i can cut the letters out of fondant and put them on the decorated board, but kinda wanted to do something different, was thinking about maybe a dog house behind him, with a sign saying that. any ideas how i might be able to do this easily?

ok well i winged it (is that even a word??) check it out in my pics turned out pretty cute i think!
