That is a great idea, if you don't mind I would like to do the same thing. I researched the topic and found this site http://www.joyremembered.com/family-letters/66/, the article you have mentioned is probably an archived edition and can be found at http://www.parenting.com/. I hope these help. I would like to find the back issue you got this from, it sounds very interesting and fun for the whole family.
