Cut a piece of thin cardboard into a strip that is 1.5 inches wide by 8 inches long.
Peel the backing off two address labels and attach them to the cardboard, 1/2 inch from each end.
Write your phone number beneath the address labels.
Cover the strip of cardboard with shipping tape on both sides; this will make your luggage tag waterproof.
Fold the luggage tag in half so that your address labels are facing outward on both sides.
Slip the tag around the handle of your suitcase or duffel bag and secure it in place with another piece of shipping tape.
