This is another story about spreading love one piece at a time: http://www.loveyou2.org/.
"What began as a fun love note for my kids has turned into a passion for finding, documenting, installing and sharing love notes. You can join me changing the world one love note at a time."
Shannon has been going at it since 2010 and it has expanded into other things, including a Ted Talk.
Thanks for sharing this, Janice!
