Had to share a link to this project:
That was my idea! I wrote to Family Fun a few years ago when they asked for Valentine crafts. It was almost 10 years ago since that is my maiden name in the little blurb! Too funny that it's still on their website. I think I got some money for contributing.
I was thinking about doing something like this in my classroom where I could write a message on a heart for each student in my class. Then I could put them up on Valentine's Day to surprise them. :)
