You could, of course, purchase another pot knob, or retro-fit one from a different pot, but that’s hardly the point. If you make one yourself you could make it neon pink, or put your family name on it, or put a snarling bengal tiger face popping out of the top, which would be sweet.
I also shamelessly copied this hook style from @Cotty s thread. Great for little hands to hang things up on.
