I read once that the mark of mastery is knowing when a piece is “good enough”. As an aspiring wood turner I spend excessive time trying to make sure every piece is perfect. But, in order to be commercially viable, as well as retain some sanity, a craftsman has to get to the point where he understands when a product is finished.
The vast majority of consumers will not understand or appreciate the full extent of the craftsmanship that goes into a piece; nor will they see the flaws in their new acquisition. Only the craftsman will recognize his mistakes in the end product. The customer only sees what is, not what was intended or could have been. For artistic works this is especially true. A work is purchased because it spoke to the buyer. It is perfect to that person.
