Add a touch of elegance and sparkle to your garden borders by incorporating sea glass collected during beachcombing. Sea glass, with its smooth and frosted appearance, comes in various colors and sizes. Arrange the sea glass pieces along the edge of your garden bed, either burying them partially in the soil or securing them with stakes. The sea glass border will catch the sunlight and create a beautiful shimmering effect in your garden. It's a unique way to showcase your beachcombing treasures and bring a coastal charm to your outdoor space.
