So say I have a pot I want a lid for and I want to cut out and hand build that lid. A simple lid, nothing fancy. And I want to put a round, normal curve in that lid. Once I cut out the lid, I can simply put the slab over an object like a bowl to get the curve, but how do I know how large to cut that lid before curving it? Am I making any sense? Cutting to size when flat wouldn't work, cause it will be more narrow when it has a curve in it. Yes?
This is probably ridiculously simple and I'll be really embarrassed that I couldn't figure this out, but I've been trying to figure this out for a few days and I'm stumped.
