Lunch box notes! This would be a great crafty idea for a parenting group. Draw out their creative side and provide materials and encourage them to share their own (esp those who do stamping/scrapbooking, they have lots of neat stuff!) and make cute lunch box notes for their kids. Great back to school craft. Could do a program for both kids and adults at the same time, kids decorate lunchboxes, parents make the notes that will go in!
