It's important to send Christmas cards early, ideally before December 1st. This will give your friends and family time to receive your card and appreciate your gesture before Christmas arrives. It's also a good idea to write a personal message on the card, expressing your feelings and showing that you care. You can also include a photo of you and your family, if you'd like. Sending a Christmas card is a wonderful way to spread holiday cheer and let your loved ones know that you're thinking of them.
