In an article in New York Woman magazine, ophthalmologist Alan J. Friedman said that plaid is a complicated pattern for the brain to interpret. ”It may cause some degree of psychovisual discomfort,” Friedman said.

That probably spells caution for its use in home interiors.

Layering plaids a la Ralph Lauren may be beguiling, but some designers suggest that casual mixing is more difficult than it looks.

”Layering is tricky,” said New York designer Mario Buatta. ”And you`ll probably get tired of an all-plaid look.”

Instead, Buatta recommends a moderate presence, such as:

– Plaid towels in the bathroom.

– Throw pillows, throws or ottomans are a nice way to introduce the pattern. So are smaller accessories, such as picture frames, boxes, dinnerware and mugs.

– Try a plaid on a window valance or a balloon shade.

– Use fabric swatches with plaids of different scales to get a sense of how the pattern looks alone or in combination with your existing fabrics.

– Plaid as the only pattern in a room can be striking, depending on the colors used.

– Buatta combines plaids with chintzes, in upholstered pieces or in window treatments. You have to experiment with scale and color, pulling from the dominant hues in the floral pattern to get the complementary colors of the plaid.

– Plaid, like chintz, can soften the look and feel of furniture.

– Plaid wallpaper looks terrific, especially in a study or a boy`s bedroom, Buatta says.
