When cutting chair parts that have a lot of shaping one occasionally will cut into the wood blank and discover ingrown knots or flaws. Cherry is particularly good at disguising problem areas. So when making a run of chairs it can save time to make an extra set of blanked out parts so there is a substitute.
We had a set of eight dining chairs to do and cut out parts for nine. As it turned out all the parts were usable. So there was an extra chair to be made.
I decided to have a little fun with the “orphan” and put a big grinning mouth on the back. This is my dental chair.
