So I made luggage tags like these:
The image represents what it looks like in its finished state. The right side is twice as long. Engrave your name and address on half, an image on the other half, fold over and glue leaving the tail on the left side to wrap around a bag handle. Originally, I was going to add stitching holes, but there wasn’t enough time.
I thought there was no way it was going to make the first leg of my trip, but the one on my checked bag survived 2 United flights, 2 Norwegian flights and 2 EasyJet flights. Maybe I was just lucky or maybe it is more durable than I suspect. Assuming a luggage tag is not your intended use case, what is?
