Good idea on the plain paper and elmers. Guess I never thought of that?
On occasion I'll make out a label or two when giving them to a friend as a sampler pack. Usually add some humorous crap on it as well. Found a coat of arms graphic for my name and spin everthing around that in MS Publisher.
For my own consumption I don't bother. I keep track on what is what by color code with a little splotch of enamel paint on the cap for whats inside. (Wife has a wide variety of model type paint) Right now its:
Green - Oatmeal Stout
Gold - APA
Yellow - Negra Modelo clone
Plain - Honey Rasberry crap from hell (think it's bad or something...)
Tell ya, this works great for keeping track. Just started this about 2 weeks ago as the stock has grown.
