"Divide and label" is Sarah Sirlin's philosophy. "It's the key to being organized," says the 32-year-old graphic designer in Pittsburgh, who runs her stationery business, DSIX Design, out of her home. She believes in low-tech labels. "I write on the sticky part of a Post-it note and cut it to approximately 1 1/2 by 1/2 inch," says Sirlin, who also labels the fronts of shelves and storage boxes in a large cabinet, as well as the two-inch-deep drawers of her Bisley filing cabinet. "Computer labels would look better, but I want my system to save me time, not create more work for me."
