2. Seashell Shadow Boxes

For a more tactile and personal touch, seashell shadow boxes are a lovely choice. You can collect shells from your own travels or purchase curated ones that align with your color scheme. Frame them inside simple glass boxes or natural wood shadow frames and arrange them in a grid for a gallery-style display.

This DIY-friendly decor idea adds a personal and textural element to your wall while maintaining that breezy beach charm. Combine small and large frames to create depth and interest. To complement the coastal palette, choose light backgrounds like cream, pale blue, or sandy beige inside the frames.
