I've got a Chrome Metropolis bag (please save your applause) . . . and I want to write "CAR-FREE" across the main flap of the bag. Any ideas on how I can do this? I'm looking for a durable method. I can always resort to simply using a Marker, but I was hoping that there is a better way. BTW would reflective tape stick to the CORDUA (or whatever the material is) for a long time?
