To use these Christmas Tree Meditation posters and prints, simply find a nice spot on your wall to hang them. Make sure the wall is clean and dry before you hang them up. You can use your own frames or leave them unframed as they are. As for maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors over time. Also, keep them away from moisture to prevent damage. If there is dust on the prints, you can gently wipe them with a soft, dry cloth.
