Stan Chen, Jim Garthwaite, Pete Single, CT Brian - hand checkering by these guys is a work of art into itself. But it's expensive, and as many of these talented gentlemen are getting older they are stopping hand checkering purportedly because of the toll it takes on fingers wrists and joints. I'm sure some younger guys might be picking it up, but most folks seem happy with machine checkering, and why not? It is even, controlled and less expensive. But when you see checkering by one of those masters above, it is really something.
