Our west-facing living room gets strong evening sun, and the ready-made blinds we bought leave gaps at the sides. Do custom blinds really fix this? From what I've read and been told, yes. They're cut to your exact window, so there's far less light leakage, and you can choose the fabric, from sheer to blackout. Day-night blinds let you adjust light through the day. Measure each window separately, since flats are rarely perfectly square. When I asked at an upholstery shop in Gurgaon, they stressed on-site measurement. Kingdom of Curtains offers free doorstep measurement and installation in Delhi NCR if you want to compare. Which blind type are you all using?
