That's been a really useful, informative film - many thanks for posting.
I noticed that you do not us the natural curvature of the piece of wood for the bowl of the spoon. I was wondering why that was? I was lead to believe that if you cut across the grain of the wood, you weaken it; as a result, I have always 'followed the grain' when carving the bowls of spoons, often using the wood to define the shape of the bowl. I'd be really interested to hear your thoughts on this and, in the meantime, I might try roughing things out in the way you demonstrate.
