plaid
A pattern made up of many perpendicular vertical & horizontal lines of two or more colors. Compared to the uniformity of a check pattern, plaid features distinct irregularity in the width of its lines, and the colors used may not be divided neatly by said lines.
For plaid clothes, see plaid clothes. Otherwise, tag the specific object such as plaid umbrella or plaid curtains.
