Enhance your garden's charm by decorating a birdhouse with recycled wine cork coasters. Glue the coasters onto the roof or sides of the birdhouse, creating a textured and visually appealing surface. The cork material provides insulation, keeping the birdhouse cozy for its feathered inhabitants. This upcycling project not only adds a decorative element to your garden but also promotes sustainability by repurposing wine corks in a creative way.
