Long after the last coats have dried on your new paint job, you can still have easy access to the color names and numbers for touch-ups. Save the wooden stirrers you used to mix the paint, let them dry, and then write the names and numbers of the colors on the ends of the sticks. Use a length of twine to bundle the sticks by room.
