Centering means now I can get to the pulling, shaping, and that form I have in my mind. How well I centered directs how well these next steps go. For quite a while my centering was loosely centered; just enough to start working, and rarely centered well, and then only by grace of unknown forces.
When it finally clicked in for me was maybe three years after starting and opened a world of possibilities with no more thick-thin, no more too wet clay to pull, and less slumping from overworked clay. Boy howdy, that was a day to remember! Robin Hopper gave me what I had been missing in a Ceramic Arts Daily video and I was off to the races.
