In pleasing artistic patterns, geometric wallpaper makes a statement without shouting too loudly. These designs celebrate the best of traditional and contemporary techniques: use them to add texture and as a counterpoint to neutrals. Go bold with dark and light for a Scandi-noir effect, or pick a colourful motif for a playful feel. To create a sophisticated décor, opt for a chic micro or block print from manufacturers like Zoffany, Nina Campbell and Cole & Son for shades of classical architecture and refined styling.
