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!
Use old jeans, cut into squares, add some batting material to the center, sew edges together. Either sew or draw the "X" and "O" onto them and instant tic tac toe game for kids! - Cool to do with beanbags too.
