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!
My own efforts at melted crayon art for our daughter. Board is the normal backing to the picture frame. Painted with white chalk paint. Letter and umbrella blanks cut out of cardboard and the rest is obvious from the pics.
