I was asked to do this for an office party to celebrate the fact that they can move back into their offices now that the ceiling panels have been replaced since they came down in an earthquake. They wanted a ceiling panel and it was short notice so this is what I came up with. Cut out the holes with a straw and then placed the fondant on top of the already carved/iced cake. I used a bit of MDF panel door I had around and got the skillsaw to it to rough up the ends and make it look like it was broken. Bit of an excuse for a bit of knees up/stress releiver I think.
