There are challenges with pinching and sometimes a pinch pot gets completely out of control. This video shows an easy way of how to do in-pinching to get the pinch pot back under your control.
With pinching, you can develop "eyeballs on your fingers", as Antoinette always tells her students. Pinching skills will help you to judge the thickness of a wall or a bottom on a pot - helping you with trimming.
Antoinette Badenhorst presents an online workshop where she teaches potters how to pinch a complete functional teapot with clay (Pinching teapots for Beginners).
