). A bottom sheet is laid above the
mattress, and may be either a flat sheet or a fitted sheet (a sheet which has been sewn with elastic or a drawstring along the hem of the top, sides and bottom of the sheet to prevent it from slipping off of the mattress). A top sheet, in the many countries where they are used, is a flat sheet, which is placed above a bottom sheet and below other bedding.
History
The term ''bed sheet'' was first used in the 15th century. Bed sheets were traditionally white and made of cotton, linen or silk, however, now various colors and patterns are used.

, to be used only as a bottom sheet. The fitted sheet may also be secured using a drawstring instead of elastic. The purpose of a fitted bottom sheet is to keep it from slipping off the mattress while the bed is in use. A particular way of folding and tucking while making the bed, known as "hospital corners," is sometimes used when the bottom sheet is flat rather than fitted.
Usually a flat bed sheet is

only. When placing a flat sheet on a bed, the manufacturer has designed the printed side to be softer, and thus it should be placed on the bed printed side "down". When folding back the covers, this also allows the printed side to show, for aesthetic purposes. When one
makes a bed, the patterned or
monogrammed side of the top sheet is placed facing down and then the top edge is folded towards the foot of the bed, exposing the design.
In the US and Canada, sheets are often sold in a four-piece set consisting of a fitted sheet, a flat sheet and two pillowcases. In China, a four-piece set consists of a duvet cover, two pillowcases and either a fitted or flat sheet. Fitted sheets are gaining popularity due to their ease of use. Use of good quality elastic make fitted sheets durable.

Construction
The quality of bed sheets is often conveyed by the
thread count
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.
* A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or man-m ...
—the number of threads per square inch of material. In general, the higher the thread count, the softer the sheet, but the weave and type of thread may affect the "hand" of the material so that a sheet with a lower thread count may actually be softer than one with a higher count. Yarn quality also plays a part in the look and feel of sheets, as finer yarns tend to create a finer sheet fabric. The ply also plays a role in how heavy the sheet feels. Ply represents how many fibers are twisted together as the sheet is being created. A 2 ply 300 thread count sheet will feel heavier than a single ply 600 thread count sheet.
