Well, from my proudly hillbilly family I learned a lot. Books were a lot of help too, starting with MY SIDE OF THE MOUNTAIN by Jean George. So was Mors Kochanski, Richard Graves and Larry Dean Olson. Then, lots of practice! Some things I could make work, some things I could not. The next step was sitting with people who knew things, like Marty Simon, Tim Dilard, Ann Gill, and MANY others! Finally, I learn much from teaching- both deepening stuff I already know and learning new things from students.
