Ditto to waiting, till your skills are up. I was eager to try some beautiful coral slabs I had. Well I have only one left. And it is staying where it is. The others are gravel. If it is knappable, just tell it when the time is right, and you are capable of releasing it, the arrowhead, will emerge. It's ok to talk to the rock. I do it all the time. You know, " You son a @#%$# !!!!I was almost finished with this side of the barb, when you decide to let the other side come off!!j You dirty little Piker! Etc. Sometimes it is amazing at the new words you can come up with, and not have the slightest idea of what they mean exactly, except to represent your anger, and disappointment.
I have quite a repertoire, of odd words.
Sometimes I will practice them on myself, as I walk by the pile of gravel made from coral
........I would definitely agree to wait. There are a lot things to learn yet. Shannon did seem to pull some ancestral gene out, and learned quite fast, and well. As for slabs, try em, and also get with some one to learn to spall, and percussion knapp, to thin down the spalls, and do the final finish with pressure flaking. Anyway, good luck, and don't let it be a sticky wicket in your progression to being a proficient knapper.....
