I was talking to a guy yesterday who had them do up a nice muskie for him...they didn't have a mold that was close enough, so he paid extra.
I think to go free, or even discounted....it's going to have to be some kind of record, and you're going to have to let them either make duplicates for shows and advertising, or take yours around to different shows for their display.
Hmmm.....wonder if we'll see a 27.5lb sheepie come from their shop any time soon?
