Hi guys i just got into pouring my own soft plastics. I have a couple aluminum molds i have seen a lot of videos on making molds out of plaster of paris. I wanted to make a 3 inch and maybe a 4 inch worm mold. My question is since most of the bait companies have these worms is it legal for me to use them to make the mold? I know things like horny toads are patented just cant find anything on worm molds or fluke style baits. Thanks
