There's alot more than just feathers on a well crafted tying bench. However, in todays market, specializing is a must... to try and do everything well is a fools folly.
As I've mentioned before, my passion is the birds. Finding sourses of quality feathers, cleaning them, and packaging them takes time. And the fact of the matter is that I just don't have time for the threads and hooks and such.
So I'm leaving it to others to handle the rest..... and here are some links to what others have said to be the best sources from everything from hooks to books. If you know of other, please drop me a line.
