Every year when I was a little my Gram would give my siblings and I a Christmas ball. These were usually dated with our names on them and specific towards our interests. My mom used to hang them all on the tree so each year we could count on 4 more ornaments. When I got married my mother happily handed over mine.
My favorite one (and always has been) is my very first Christmas ball. I love everything about it. I love the how it says "baby's first Christmas" and how wonderful the drawings are. They just don't make ornaments like this anymore.
My mom has carried on this tradition by giving ornaments for my girls. They loved decorating the tree and finding the ornaments with their names on them.
