Bring a coastal vibe to your cottage kitchen by adding a vintage sign collection. Choose signs with beach-inspired designs like seashells, anchors, or lighthouses. Hang them on a weathered wooden plank or above a rustic kitchen table to create a relaxed and beachy atmosphere. Combine the signs with nautical-themed decor, such as rope accents, blue and white striped linens, and seashell accessories, to complete the coastal cottage look.
