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!
"Rainbow at the End of the Pot of Gold" Run out and grab a few buckets (craft store or dollar store), some gold spray paint if you can't find gold buckets. Add coloring pages, rainbow of crayons and you have a great treat for when the kids get home!
