Soft, sandy rhythm with a coastal wink. Sandy Lines sketches a relaxed herringbone from hand-drawn lines—calm enough for whole rooms, characterful enough for a feature wall. Designed by Cass Deller and available exclusively at Wallpaper Trader, it brings an airy, beach-house ease to bedrooms, living spaces, hallways and sunny nooks.
