Looking for know how to make my own jig molds, didn’t see any such thing PINNED

Looking to make various sizes from 200 - 350 gms maybe higher for slow pitching, knife and flutter. I’ve seen mention of both using silicone and bondo, not sure which would be preferred these days ( maybe new products out ). Hopefully there will be some pointers in the discussion(s). These are for personal use so don’t need to be perfect. I did see a very informative post regarding foiling of jigs but will try to look around for any innovations or tricks since that is a 4yr old post. Thanks for any LINKS
