Send Free To a Fabulous Niece - Happy Birthday Wishes Card to Loved Ones on Birthday & Greeting Cards by Davia. It's free, and you also can use your own customized birthday calendar and birthday reminders.
Scripture Calendar - Love this idea! If anything you'll memorize 12 verses each year. Could add a numbered blank list on each page to write things you were thankful for that day (fill up the whole month)
