Blech. I'm not a fan of it when the best advice someone can give on learning a particular type of folk magic is "Find a teacher". Nice.
Specific magico-cultural religions aside, that kind of advice falls short if you live in a geographic area where the local magical, occult, and/or pagan communities have little to offer in that regard, and you can't afford air fare to other parts of the country (including vehicle transportation and lodging) on a regular basis. And local magical shops can fall short too if they only carry the cheapo mass-market tripe (Witch School, Ravenwolf books, etc). Don't even get me started on stores like Barnes & Noble.
And yes, I do speak from experience. Thank the Gods for the internet!
