I know nothing about making jigs....just wondering where and how do you get the molds and how do you get started?
Check out Barlows or Nettcraft or Zeiners for Do-It molds. Or go to Do-it Molds - Fishing lure and jig molds to see their full line. Do your decision making at the Do-It site, then order off one of the other other three sites for your best savings. Jacobs baits has lead molds too but they're three times as much money and don't do any better on quality than the Do-It molds. Do-It has a much better selection too.
