These are the thank you cards Mitch sent out after his birthday. Although I don't do it nearly often enough, thank you note writing is important to me so I've tried to encourage it since Mitchell was just a little guy. Before he could talk, I would write the note and then let him scribble on it. Although he still can't write, he is now old enough to formulate a really cute and sincere sentiment of gratitude which I simply write down for him. Also, I still let him decorate the notes which makes it all the more charming.
