If you build something that will last 50 years or longer, it should also be looking nice for a very long time, so we build tables which we think will be looking good in many years as well as they do today. That might be very hard to do, but we try. For me it would be a success if the grandchildren still like the table.
What better way to honor the life and death of a tree than to turn part of it into a beautiful and useful object? A humble sometimes very long life is there to be shared.
