While writing a Christmas letter to your brother, start off by asking about his health. Then investigate whether you will be seeing him soon or not. In the second paragraph you can write about all the old memories and how you would love to see him during this Christmas since you miss him. Bringing back past memories will make the card extremely special and emotional and on this occasion you should do that in order to let your brother know how much he means to you.
Sample of Christmas letter for Brother
234 Private Lane
I am writing this letter to wish you a Merry Christmas and hope that my letter will find you and your family in good health.
On this special occasion I would like to let you know that your little brother is missing you a lot and I am hoping to see you at least after this New Year. I know that you are extremely busy with work and it is hard for you to come here on every Christmas but it’s time that you visit your old home since mom and dad are missing you a lot and we haven’t spent the Christmas together since the past two years. It will be even better if you can bring your life and kids along since we love their company. Little Sarah must be missing his uncle and I would love to give her a lot of presents during this winters. Please do write back and let me know when you are planning to come back.
Lots of love for little Sarah and Johnny, who I am sure has grown old enough to ride a bike. Merry Christmas to all of you and I hope I see you all within the next month.
