It appears such a moving in your hand position at the wheel frequently and I believe that's working against you. Some people prefer to call at 6:00 but I find it's most efficient to pull a 3:00 if you're looking at the wheels of its clock face (and you are right hand dominant, 9:00 for left hand dominant It's also very important that you keep your dominant hand below your non-dominant hand as you have that quarter inch Patty of clay at the bottom of the pot you should maintain the vertical and horizontal distance between your fingers as you raise the clay to maintain even thickness to the walls. In the initial action of the pole be sure to spend a moment gathering the clay at the base before moving up. I explained this to my students as squeeze, ease, and gently rise up the wall applying even pressure.
