What fun it is to sit down at Christmastime and write a little something to the people who have contributed to your happiness throughout the year. Of course, it would be more fun if you didn't run out of ideas for what to write in your Santa Christmas cards. Sending holiday greeting cards to loved ones has long been a Christmas tradition, and for good reason: it's a wonderful way to show your friends and family how much you care. There's nothing more thoughtful or personal than receiving a one-of-a-kind DIY Christmas card, whether it's paired with one of the season's most popular holiday gifts or a crafty Christmas gift.
