The key purpose of curtains are for enhancing the look of the bland looking rooms or interiors. One finely designed or colorful pair of curtains can change the whole concept of the interior. They are fabric panels which are often sold in pairs. Curtains are available in wide range of widths, lengths, fabrics, colors and patterns; they are very useful and a popular choice for every nuke and corner of the home, even bathrooms and kitchens (the short, sheer curtains that cover only the bottom half of a window over a kitchen sink, frequently matched to a decoration across the window’s top, are called café curtains.) In the bedroom, you’ll likely use curtains over another window treatment, such as a blind or shade, because curtains are made of lightweight fabrics – some are very sheer — and are not lined.
