This is something I am still getting better at: knowing when a handmade piece is actually finished.
I can always find one more thing to change. Move something a little. Add a detail. Remove a detail. Try another version just to see if it is better.
You can do that forever.
Is the change fixing a real problem?
The question I try to ask now is whether the next change is actually solving something.
Is the main subject unclear? Is one area too bright? Did a detail disappear in the engraving? Is the composition unbalanced at the real finished size? Those are problems worth fixing.
But if the main idea is clear, the piece reads well from a normal viewing distance, and nothing is genuinely bothering me, there has to be a point where I stop.
Finished does not mean perfect forever
I can look at an older piece months later and think of something I would do differently now. That does not necessarily mean the original piece was unfinished. It may just mean I learned something since then.
That distinction matters when you make physical work. There is a difference between improving a piece and being afraid to commit to it.
Our process includes testing the design against the material and the final size, because that is where the most useful corrections tend to appear.
I still do not think there is a perfect formula for knowing when to stop. But I trust the physical object more than I trust the urge to keep adjusting a file simply because I can.
