Treasure Table recommends that you color code your dice. What the hell does that mean? Why, just make sure that in your dice bag all your 6 sideds are one color, d4 are another color and so on.
While this seems a bit over the top, I think it is a pretty good idea. However, one of the joys of having lots of dice is the rainbow of possibilities.
Oh, and I never have a bag in which I put my dice anyway. They end up throw willy nilly in my computer bag whenever I'm off to game. That means that every 6 months I need to get more dice do to attrition.
