I'm not sure where he gets his patterns, but I think he glues them to the oak and then cuts through them as he works the piece. This and bowling are his 2 hobbies. His knees may not let him bowl much longer. He has told me many times that he's surprised his hands are still steady enough to do this work. He's also told me many times how grateful he is that there's still something he can do that's creative and makes people happy. That one was so intense I'm not sure he'll do it again.
Thank you all. I think I'll copy out all the responses and send them to him in an email. Y'all will make his day.
