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!
Garland from Woven Paper Balls-- These are made out of paper and one piece of tape. You can cut your own strips (mine are wide and long, which yields a ball that's about 1 in diameter) or use shiny paper ribbon.
