Sometimes you have to wedge the clay, even when you know it's already smooth, just to feel the resistance and remember what you're fighting for. This one isn't done yet. More to say. The glaze will always show the flaws, no matter how expertly the seam is hidden. Better to leave the thumbprint, the wobble, the mark of the hand that made it, than chase a perfection that isn't real. The crack is where the light gets in, and sometimes, it's the only thing that makes it honest.
