Started by my godmother many years ago was our practice of putting an ornament on one of your gifts. She started doing this when I was about 10 or so. When Matt and Em (our cousins) came along, we started them from the beginning. What you end up with is an ever-growing and very eclectic collections of ornaments. When Matt and Em have their first Christmas in their own home, they'll have a collection of ornaments going back some twenty years.
