Most of my points are kinda "clunky"-looking.  Sometimes I get a real cooperative rock and it turns out pretty nice.  I've sold a few things I've made from the booth at gun shows, but mostly give them away in the demos.  
 
Another guy and I do classes for school, tour, encampment, and Scout groups and some more detailed things for a Scout badge of some kind.  Some of the kids we've taught have even picked up primitive bowyery and knapping as a hobby.  Just remember:  It's simple, but not necessarily easy.
