I do the same as AJ but don't put them in a plastic sleeve, that's a good idea, cause I've got some wax and oil on a few of mine (actually on a LOT more than a few). I use the larger 4x6 cards, can put more info on them, then bought the alphabet index cards and keep them in a recipe box. I've got three of these darn boxes now, since I've changed wax 3 times, and now I have to start another one for the new wax I'm doing. Sounds crazy, but we all know the work that goes into testing, and how important notes really are, so if I ever decide to go back to one of the other waxes, I'll be set to go.
