Create a mood board for a cozy cottage-style bedroom. The main color scheme should be black, with a balance of dark tones and contrasting highlights to create a sense of depth and warmth. Feature elements such as a black wooden bed frame with a rustic headboard, thick black curtains draping by the window, black chalk painted walls, a black braided rug on a wooden floor, black cast iron accessories and lantern-style bedside lamps. The bedding can add a touch of light with white or grey tones. To maintain the cottage feel, include some vintage furniture pieces and natural decorative elements.
