Christmas Tree Flocking is a process where a white, snow-like substance is applied to the branches of a Christmas tree to create a more realistic and festive appearance. The flocking can be made from various materials, such as cotton, polyester, or even snow itself. The flocking is sprayed or sprinkled onto the tree, covering the branches with a layer of "snow" that can be easily removed when the season is over. This process can also be used to create a more lifelike appearance on artificial trees, making them look like real trees covered in snow.
