I love you clothes pins: Write a message with a FINE POINT sharpie so it doesn't smear. Write "I love you" on a paper. Cut it out, and hot glue it to the clothes pin end. Would be cute for a care package!
I'm sure the airport security folks would have a blast with you, but this is still a great idea. The frustration-free Travel Security Belt is the traveler’s ‘insurance policy’ against a stolen or lost wallet. Fits cash and paper copies of your IDs.
