sooz. i havent made mine yet so dunno how it will turn out but i am doing a rectangle shaped choccy cake. Then going to just ice it with cream icing. Then using a piping thingy pipe around the edges in red, and i have a round wiggles template to go in the middle as well as a big red car candle to sit on it. so pretty simple but hopefully will look effective.

i think a NUMBER 1 is not so hard, u just need the right size tin and then cut one if it for the top part of the one. u can do what ever flavour cake u prefer, then just ice it pink, put some little faires or sprinkles on it.
