Thanks every one.
You can read a little more about my quiver in my arrows post on the arrows section. It is made of hickory bark. Accually from the same tree as the bow. I used my knife to shave off the grey bark and that revealed the nice tan bark underneath. After that I just wetted the dried bark and put it around a log and let it dry stiff. It is not stiched in a cylinder. Then I made a bottom out of twined corn husks and sewed that into the bottom. It is very simple and would be very easy to make with only stone tools.
The bow shoots great. Very accurate. I read that you had to spine arrows to make them accurate but I did not and they fligh very straight. Maybe because the bow is only one inch wide.
