Hi All Experts.

I saw a video on youtube in which a guy created his own custom pan using cardboard and then wrapped it completely with aluminium foil. I have basically 2 questions

• is it safe to do it? he actually baked a cake but still curious, can we use cardboard (covered with foil) inside an oven?
• Is there any better way to make our very own custom pans? cardboard are not reusable ones

You can buy disposable pans for cooking cakes, breads, etc. these are basically cardboard. 

it is far more practical and cost efficient to just carve the cake in the shape you need vs a custom Pan. But if you really wanted to do it you could contact a metal fabricating shop. 

I agree with jmt1714, why not just carve your cake.  If you use a nice, sturdy recipe, it is easy and fun to do, and you can get more detail and a more realistic result.

I often used foil covred cardboard to divide flavors in a pan so why not make the whole shape you need?   I'm not a good carver so I'd probably make a shape than try to carve it out :)  Just make sure you use 2-4 layers of foil over the cardboard.
