Our flat has a terracotta feature wall, a sand sofa and a deep teal armchair, and I’d like curtains that look planned, not accidental. I’m considering a two-tone curtain, sand with a wide terracotta border, with straight seams, so it echoes the room. Would it be better to keep it plain and let the furniture do the work? I’m also wary of strong sun fading saturated colour. At a drapery store in Gurgaon they suggested lining. Kingdom of Curtains does free doorstep consultation and installation across Delhi NCR, so I may ask them to bring colour cards home. Any experience with colour-blocking at the window?
