How do you keep track of Which Flavors are in each Tank if you have many?

I have a ton of those blank self adhering return labels on sheets for the printer, (3'X1"), and since I do a lot of mixing in the tank, (12 eVods), I need to be able to keep track of what all is in any particular tank. I write the combination using abbreviations across the short end of the address label and then snip it off, 1/8"x1" and then peal and stick. This way I can change labels many times in a day and it's not too much work to do so.

The only problem I have now is that I forget what my abbreviations are, (DBL+DGNL)!!!!!
