I have been trying for days to figure this one out; maybe someone out there can help me.
I'm planning to make a mushroom cake and I have this idea in my mind that the BOTTOM of the mushroom cap tier needs to have a gentle wave to it. I do not want it flat on the bottom.
I've made a pillow cake, so carving the cake does not scare me. But what the heck can I use for a cake board, to support the tier so it holds its shape?
The only ideas I've had (all of them bad!) are these:
1. An old 45 music record, somehow melted and warped similar to the shape I'd need. (This would have the advantage of having a hole in the middle for dowling the cake. I'm thinking maybe I could cover the record with multiple layers of plastic wrap OR seal it with a coat of food-safe varnish.)
2. Making something out of paper mache and then sealing it with food-safe varnish or plastic wrap.
3. Buying a piece of metal and cutting with tin snips, and trying to bend it into the shape I want. Bt then how would I put the hole in the middle? (I'm not so skilled with power tools... nor do I actually own any! 
4. Going to the local acrylic and glass shop, so see if they can custom-make something for me (I probably couldn't afford it, though!)
5. Taking the lid of a cheap round tin, and trying to form it into the correct shape ... but then I'd need to put a hole in the middle of it and like I said before, I'm not sure how to do that.
Anybody ever done something like this before, or have any ideas or advice for me?
Thanks in advance!
