Learning to step away from a creation and declare completion can be hard for an artist. I know I sometimes struggle with this concept and have heard it expressed by fellow creators. Overworking clay can lead to disastrous results. It's probably why I like to make multiples of a particular shape. It gives me the opportunity to satisfy that urge to 'perfect' the final outcome.
Lately, I've been reworking pot shapes and designs I've made in the past with techniques, glazes and skills I currently favor. This gives me an opportunity to repeat a favorite shape and adapt it to a fresh and updated look.
This journey includes looking at wheel-thrown shapes I've made and translating them to my current hand-building methods. Sometimes the conversion works beautifully. And some pots are just meant to be thrown on the wheel.
