Setting up a cozy coffee corner sounds like such a great idea! Moody wallpapers are perfect for adding depth and a touch of drama—they often feature rich colors like navy, charcoal, or burgundy, with bold patterns like florals, abstract shapes, or vintage prints. They’re not necessarily too dark for small spaces if paired with warm lighting and lighter accents. Check out boutique wallpaper shops online; some offer samples so you can test before committing.
