got it at lure craft.i don't have any recently new molds yet,but i have plans for making a simple mold with the silicon putty i have.all my molds are hand pour open style ones except for the glass tubing i use with a plastic syringe for trout worms.the small mold i think is under 10$. here's a link to it
5x237 - LureCraft i haven't got to try the small grub and shad shapes yet.a 1/64 jighead should fit the small grub good enough.
i got 2 books about making all sorts of different tackle.in one of them it talks about making molds out of silicon for jigheads!so if i ever want to make my own jigheads can use silicon stuff.
