so im a 1/4 way thru a batman sculpt, and i want to eventually turn it into a wearable mask, was looking for suggestions on what i should eventually cast it in, its going to be a one off personal use then display piece. so im open to suggestions of all sorts. Whats reasonably inexpensive for a one off piece. The reason i need it to be reasonably inexpensive is because my Fiancee will kill me from spending to much on something like that when we are planning our wedding. So any suggestions will be appreciated.
