Aside from woodcarvers that have books, DVDs, articles, which I follow faithfully, I wanted to mention some famous carvers whose work is truly inspiring.
For anyone that wants to see some of the most amazing carving ever done check out Grinling Gibbons. There are brilliant carvers to day that do astounding work as well but what amazes me about Gibbons is his work was done over 300 years ago and to this day is unsurpassed. It is said his foilage in some carvings was so delicate that they would sway in the wind when carts on the street would pass. David Esterly is a moden day carver who follows Gibbon's type of carving and is amazing as well. Check out his work.
Another carver if you are into period furniture is Samuel McIntire. New England, 1700s era, amazing carver.
And I would be remiss if I didn't mention Michaelangelo. Incredibly brilliant carver and sculpturist, to the point of being scary that he had that amount of ability. Truly a God-given gift. Most people don't realize he also did wood carvings.
