The Taunton press also produce a Jeff Jewitt DVD "Hand Applied Finishes" where he demonstrates French polishing. I haven't tried his method, it looks great, but time consuming.
I'd have thought the DVD is worth getting, I don't know how you could explain it properly in writing. I've got a few of the Taunton DVD's and they are all good. They take a long time to arrive if you order them from the USA, and only play on a region free DVD player.
