To complete the coastal nautical theme in your kitchen, choose tableware and accessories that evoke a beachy vibe. Opt for dinnerware with nautical patterns such as anchors, sailboats, or seashells. Use striped placemats or table runners in shades of blue and white. Display coastal-inspired accessories like a glass jar filled with seashells, a ceramic fish-shaped dish for holding condiments, or a rope-wrapped utensil holder. These small details will tie the whole theme together and make your kitchen feel like a seaside retreat.
