The cheer- ful woven patterns, in which stripes of different colors and widths are arranged at right angles to one another, are showing up in upholstery fabrics used for throws, sofa and chair covers, pillow and wall coverings, and as sheets and tableware. New York designer Ronald Bricke says if you're planning a plaid room, don't do the obvious. Instead, "do the extreme. Plaid can be used in strong contrasts — for example, a Black Watch plaid with deep green satin." For a "feminine" room, imagine clear pastel color walls, floral sofa, plaid open-arm chairs, muslin or organdy curtains. Tartans work well in city or country homes, depending on texture. The heavy weave and dullness of wool plaid suggests country rooms. Tartan in taffeta has a citified shine. For a room that conveys a masculine image, use a big, boldly colored plaid. Originally, the word "tartan" meant the design of the fabric, and a "plaid" was the tartan cloak that was part of traditional Scottish dress. Ascribing a specific tartan to a cer- tain clan was begun in the early 18th century by a group of Scots living in London, who wrote to clan chiefs in Scotland and asked them to select a specific tartan as their own. Before then, no clan was identified by a single tartan. Li
