Curtains and blinds block out light and drafts, as well as giving you more privacy. But they can also be a distinctive design feature - introducing colour, pattern and texture into any room in your home. Curtain tracks and poles, too, come in loads of different designs to suit every style of interior. But if you're going for ready-made curtains it's a good idea to choose them before you buy your track or pole, as you might find they're designed to be hung from a particular type of fitting.
