Design a cohesive interior design moodboard focused on layered window treatments. The moodboard should include: A color palette featuring teal, soft blue, warm beige, and light gray. Fabric swatches for sheer, blackout, and linen materials in complementary colors. Close-up textures of the fabrics to show detail. High-quality images of curtain hardware, such as matte black and brushed nickel rods, and minimalistic tiebacks. Decorative elements like natural wood accents and subtle plant details for added warmth and texture. Arrange all these elements in a clean, visually appealing, and organized layout that serves as an inspirational design guide.
