Good afternoon, gentlemen :)
There are a lot of manuals on the Internet on woodworking, and on methods that allow you to work with methods ... A

Can you advise good manuals where you can understand well how to work with wood and understand all the basic methods :) Preferably for the level - kettle :D
Thank you.

Answer 1
