Started probly 7 yrs ago on my own. Always have hunted artifacts and always wondered how?
Finally got some teachings at knappins and it has snowballed form there.
As for teaching? Nothing works better than hands on.(SAFETY FIRST) For youngsters,gloves,plenty leather pads,and safety glasses. Try to percussion a biface and explain every move and why you are making it. Use a marker on the stone to show them where the flake should travel and why.Platfoms,ridges and grinding.
Takes a lot of time the teach and more time to learn.As long as there is some instruction,there will always be progress. They will have to hit alot of rock,have failures,but hopfully learn from them.
