Thanks for your excellent and informative posting. It's obvious that you have done a lot of work to learn these techniques, and rely on good old fashioned hand work and a lot of time to do what you do. It's refreshing to see.
Any links to where we might see some pictures of your work would be deeply appreciated. I would daresay that it would bring some work to you, if you accept comissions to do custom work for clients. I'd be tempted myself.
