You make one. Some cake shops have special cakes that turns any photograph into the frosting. You provide the photo.
Mmm cake... Looks delicious! How come I have never thought of making an LP cake? ..! I'll keep it in mind. PS: If no-one has eaten Rob yet, I'll have him.. *yummy* xD
So in essence, the fangirls are: Liz - Ches Sarah - Mike Ed - Rob Zoe - Phoenix Vdalem - Joe ? - Brad @Adam At least your family got you an LP cake even though they dislike LP.
I like Phi as well, but Rob is my favorite.. However he's got a little chubby over the years, needs a little bit more gym (he's looking good on LT shoots though xD). It's fairly easy to do for them, there's a technique that has spread recently, not sure how's it done but it's not hard, I've seen many cakes with pictures like that.
