LOL... Ollivander's only touches the surface of the real symbolism behind different types of woods, and how they're used. My current course of philosophical and religious study revolves around Druid beliefs, and they were essentially a priesthood whose spirituality centered on trees. "Druid" literally means "Oak Men". Anyway, there's a lot of background information, lore, and symbolism inherent to wandmaking. Also, you need a steady hand with a jackknife.
Is your name the same on LJ as IJ? I can friend you right away, if you wish. My friending policy is simple: If you're someone I know to be an authentic fandom person (and not a random empty-journal or lurker), I've had a conversation with you that I enjoyed, and/or if I find you even remotely fascinating, I'll friend you. I have various levels of locking, but usually only use the regular "friends" one.
