Skip, anyone can tie jig or a fly, the difference is showing them the way to do it and make a quality item. I think this is where a video done by you would make the difference. I have watched probably over 100 videos on line and I always tweak and modify them instructions to improve the durability and quality of all of them. showing a beginner tier how to do it the right way and not the easy way will only add to their interest when their jigs out fish and outlast anything they can buy.
I think kids groups and other such organizations would love to find a quality tying video and it would help them teach those interested to do it right. Having a "special" unique tie on the video wouldn't hurt, something very effective that you will simply not find in stores.
I love taking my kids fishing, now if I could just manage to fish at the same time.
