Transform your garden wall into a work of art by encrusting it with seashells. This creative and eye-catching technique will give your outdoor space a whimsical and beachy vibe. Start by preparing your garden wall by cleaning and priming it. Then, gather an assortment of seashells in different shapes and sizes. Arrange the seashells on the wall, experimenting with different patterns and designs until you find the perfect arrangement. Once you are satisfied with the layout, use a strong adhesive to attach the seashells to the wall. Press each shell firmly to ensure a secure bond. Allow the adhesive to dry completely before adding a protective sealant to protect the seashells from the elements. The result will be a stunning seashell encrusted garden wall that adds a touch of coastal charm to your outdoor oasis.
