Phillip,
I tie jigs for many reasons.
1) It is my belief that my product is far superior to anything I can buy at the store or a bait shop.
2) It helps to put a little gas in the tank when you are living on a fixed income.
3) I love to fool Crappies and Bream into hitting a jig I made
4) It is a stress relief for me.
5) I want to share what limited knowledge I have on jig tying with the youth and senior citizens who just want to tie a basic crappie jig and go fishing.
As Skip has said, Once you get into tying you tend to view all things differently. When you go to Hobby Lobby, Flea Markets, or Wal-mart you are always looking for things to "Experiment with." Barlow's, Janns Netcraft and Cabelas have good items too. There is a thread on what you may want to consider to start tying. Here it is.
For Someone New To Tying
Good luck to you and have fun.
Skip, Congratulations on your Nor-vise. I looked at one with an automatic bobbin...but it was way out of my league.
