Transform a tree trunk into a magical gateway by placing a fairy door on its surface. Look for a hollowed-out area or a natural crevice where the door can be securely attached. This will create the illusion that fairies have made their home inside the tree. The door can be decorated with intricate details and vibrant colors to make it stand out. As you walk by, you might catch a glimpse of a fairy peeking through the door, adding a sense of wonder and enchantment to your surroundings.
