That's a good start seider. Can't be afraid to turn it into gravel, though. I like to make up several just a little furthur along than that one, then work them down a little more and put them aside and keep working them in progression. If I come to a tough spot, I just put it down when I get frustrated and pick up another one. Then come back to the frustration one later. I've got a pile of pieces all @ different levels in the pit and in my knapping bag. It's kinda tricky going from stage to the next, so I like to have a few going @ the same time. keep on knappin, dpgratz
