I use these labels on everything! Just type the name of the item you want to appear on the labels. (Yes, you can type what you want on these!) I use 2x4 sticky labels from the local office supply store and load them in my printer for so many things. Here are just a few ideas, but I am sure you will find more...
These should print nicely on most any of the 2 x 4 printer labels available (brand or generic), specifically the following label numbers:
5163, 5263, 5563, 5923, 5963, 5978, 8163, 8463, 8663, 8763
Soon I will have standard labels uploaded for purchase, that I use to type short notes to parents and peal, then paste right inside student agendas.
