Create a coastal-inspired kitchen by incorporating a vintage sign collection with beach-themed designs. Look for signs with nautical motifs like anchors, seashells, or sailboats. Hang them on walls painted in soft pastel colors like seafoam green or sky blue to evoke a beachy vibe. Combine the signs with other coastal elements like white beadboard cabinets, seagrass rugs, and glass pendant lights for a fresh and breezy atmosphere.
