One thing that is identical from Christmas is the Christmas Tree. I think decorating the Chrismas tree is part of the tradition for most of the people who celebrating Chrismas.
A couple of days ago, I watched a video on YouTube from Amanda Rachel Lee. She challenges herself to decorate her Chrismast Tree only with stationary. Although the idea might sound weird, it turns out quite nice. You can check her video here.
I also remember that last year I watched a video from a BookTuber where he created his Christmas tree only from books. That kind of unusual Christmas tree feels fresh and different from the traditional Christmas tree.
Have you created an unusual Christmas tree?
