Add a touch of whimsy to your garden by hanging seashell-covered wall art. Create a wooden frame in any shape or size you desire and attach a mesh or wire backing. Collect an assortment of seashells in different colors and sizes, and use hot glue or wire to attach them to the mesh or wire backing. Hang the seashell wall art on your garden walls to create a stunning focal point. The seashells will catch the sunlight and create beautiful patterns and shadows, adding a unique and artistic touch to your outdoor space.
