I saw on tv how to make an alligator but it is an indoor one made out of paper,cardboard and glue.

I thought if I could make it and then make a mold using it..i could make alligators to go outside with hypertuffa or concrete, I have always wanted one but they are pretty expensive.

So my question is what would I use to make the mold out of.

I would like to be able to ue the mold more than once.

I have never done anything like this before..making mold or anything..Maybe this would be to big of a project but I really want to try it.
