Add a touch of seaside elegance to your garden by creating a seashell border on your garden wall. This simple yet beautiful design will instantly elevate the look of your outdoor space. Start by collecting a variety of seashells in different shapes and sizes. Clean the seashells thoroughly and let them dry completely. Next, mark a straight line along the bottom edge of your garden wall where you want the seashell border to be. Apply a strong adhesive to the back of each seashell and press it firmly onto the wall, following the marked line. Continue this process until you have created a continuous border along the bottom edge of the wall. Allow the adhesive to dry completely before adding a protective sealant. The seashell border will add a touch of coastal charm and create a visually appealing focal point in your garden.
