                                                          Many seasonal stores or catalog companies offer personalization for ornaments.  It is also very easy to write on ornaments with a sharpie or metallic marker, and this would mean your grandchildren have the personalization in your own handwriting.  Metallic markers, often have a bearing inside and you must shake them and press the tip in on scrap paper before beginning.
