I want to learn all that I can. To me marbles are still a mystery; what causes particular marks, the melding of different colors, how people can tell one swirl from another and SO much much more. All of this I want to soak up. So when I say 1 or 2 books, I guess thats really just the start of it. I'd love to put all my marbles up here for all of you to ID for me, but then I'm not really learning anything. I think (for now), I will focus more on machine mades because that is the majority of what I find while digging. That and the fact that buying single marbles that I want is pretty much out of my league.
Thanks for all the suggestions!! -James
