You probably want to share some Christmas love with them as well. Aesthetic Christmas wallpapers and Christmas backgrounds are great in this regard! Use them to "fill your heart and devices with the joy and gladness of reindeers, candy canes, gingerbread men, and mistletoe."
The purpose of this post is to share with you some good places where you can search for and access free Christmas wallpapers and Christmas backgrounds to use on your phone and desktop. I know there are several other platforms that provide these resources but I only featured those I believe are reliable and student friendly. Most of these platforms are included in my list of the best sources of free images to use for educational purposes.
