Being old school because of birth date, this has a natural appeal to me. It reminds me of those magical little pieces of paper I would get in the mail unannounced from someone close to my heart. When I lived in Hawaii I made greeting cards and what people found appealing was the hand-crafted aspect. Now, about all I get in my snail mail are bills and ads. Everything you mention in your post about doing this rings true for me. The Post Office must love you. I think this is a great idea.
