I said that in another thread, but I can't come up with anything too exciting. Tea mentioned heart shape, not too keen on that. There's round, square, rectangle, pyramid, pear shaped for some provolone and I've seen Pineapple Cheddar in a book. The only problem I see is it has to be a 2D shape so a follower will work. We could do animal outlines, kind of like cakes.
"Happy Birthday Dear" "Wow Dad that's one awesome looking cake" "Shaaa that cheddar, Baby!" "My friends were right you are stupid" "Your friends are stupid" and it continues until the police arrive.
There's star shapes, Oh I could do a star of David and sell them to Synagogue's.
