We se this all the time in shops in all parts of the country. So we set them aside for future use. The only problem is, we only remember them after we've cut up a fresh new piece, and when we do remember its presence, its actual size, or color or thickness seem to make it not usable. This is bleeding. Shuffling through these pieces again and again only adds to the loss.
Some people resist any attempt to think of themselves in terms of standards or norms.
They forget that counter heights and depths remain rigidly the same, job after job, day after day. They forget that display cases in like industries display the same products. I encounter true terror in manufacturers over the word custom, as if somehow, there is no way to ever have two cuts alike. But the finished cabinets do have like heights and depths. The real aspect of custom is a lateral dimension to fit into a space.
