You and a friend either split the kit, or each buy your own. Then you write each other letters on the little pennants. As the letters come in, you string them up. And after a while.... ta da! You have a sweet garland of letters from someone you love. How much fun is that? It would also be a great way to get kids and pre-teens into the art of letter writing. I mean, in a world of texts and tweets, it would be such a shame for the written word to be forever lost.
When was the last time you wrote a letter? I hope this inspires you to get out your pen and paper. :)
