Create a stunning beach-inspired garden border by embellishing it with seashells collected during beachcombing. Arrange the seashells along the edge of your garden bed, burying them slightly in the soil for stability. The natural colors and textures of the seashells will add a touch of coastal charm to your garden, creating a beautiful contrast against the greenery. This seashell border will not only enhance the aesthetics of your garden but also serve as a reminder of your beachcombing adventures.
