When Is a Draft Ready to Leave the Workbench?

A draft can always take one more tweak. Sometimes that improves it; sometimes it just keeps the work safely unfinished.

I’m curious how you decide when to stop refining something you’re learning to make. Do you set a boundary in advance—like improving one specific detail—or wait until the piece feels ready for another person to see?

What makes that stopping point feel useful rather than like giving up too soon?
