I use a label maker to keep everything organized; it's worked in my kitchen, my office, craft room, storage space, and bathroom. Just seeing the labels reminds me that everything has a correct place, and makes me want to keep things neat and tidy! It especially helps to keep food fresh.
I use a label maker to label all of the shelves and containers in my pantry. I label all cereal and bread with a purchase date and label all leftovers with the name, date cooked, and a "toss date". I put numbers on fresh food in the order I buy it so I can use the oldest food first.
