I figured ut the 90 degree thing!! stitched the side like I was told and sure enough it worked. So in my excitement i kept going got the excess convexity and concavity out, and ended up with a knapped marble. I wonder if the abo peoples made cats eyes and pinkies.... And just to cap it off i somehow aquired a painless 4 inch slice in my gut. How is that even possible it was on the non sharp object side
New question. I got the sides to meet but most of my flakes just stay short, i cant get them halfway across the piece like in the vids. Tried hand pressure, ishi, and a bopper, same effect. I also tried increasing and decreasing the angle of the piece to no effect. And I built my patforms all the way to the side i tried to thin.
