If you're looking to close a Christmas card, there are a few different ways to do it. The most common way is to simply write your name at the bottom of the card, or you could write a more personal message like "Best Wishes" or "Merry Christmas". You could also include a short note about your own feelings towards the person receiving the card, such as "I hope you have a wonderful holiday season" or "I'm thinking of you". It's up to you how you want to close the card, but the most important thing is to make sure it's personal and from the heart.
