In a coastal beachy kitchen, incorporating a decorative plate rack can evoke a sense of seaside charm. Choose a plate rack made of natural materials like rattan or bamboo, with a light and airy design. This will complement the coastal color palette and bring a beachy vibe to the kitchen. Displaying a collection of seashell-themed plates or colorful beach-inspired dishes on the rack will further enhance the coastal theme, creating a relaxed and inviting ambiance.
