Create a unique and eco-friendly terrarium using recycled wine cork coasters. Arrange the coasters in a glass container, creating different levels and compartments. Fill each coaster with soil and plant small ferns, moss, or air plants. The cork coasters provide a natural and breathable environment for the plants, allowing them to thrive in a terrarium setting. This miniature ecosystem is not only visually appealing but also a low-maintenance way to bring a touch of nature indoors.
