I need some suggestions on what to make mold from. I'm have made a Mustang horse emblem that will be covered with leather by my custom car upholsterer so that the emblem looks as if carved into the leather. I've used soft wood for patterns but I'm done with that phase. I don't think wood will hold up under the installation process. I've never used anything other than wood until now, so I have no experience on how different plastics (or whatever) carve.

Thanks
