In many European cultures a white, or mainly white, tablecloth used to be the standard covering for a dinner table. In the later medieval period spreading a high quality white linen or cotton cloth was an important part of preparing for a feast in a wealthy household. Over time the custom of arranging tableware on a cloth became common for most social classes except the very poorest. As eating habits changed in the 20th century, a much greater range of table-setting styles developed. Some formal dinners still use white tablecloths, often with a damask weave, but other colours and patterns are possible.
