Just read an article in the Nov 2013 issue of Popular Woodworking called "A Finishing Passion". This article is about Brian Miller who has an extensive experience working on Greene & Greene projects, particularly the Blacker House.
I took his Finishing class at Cerritos college a few years ago. He has tons of knowledge on the subject and is always eager to pass it on to his students. Unfortunately, I have forgotten most of what I learnt. Like any other skill, finishing also requires constant honing.
If you get the magazine then do read the article.
