How was a sheet made of?

A sheet is typically made from woven fabric, commonly cotton, polyester, or a blend of materials. The process begins with spinning raw fibers into yarn, which is then woven or knit into a flat piece of fabric. Afterward, the fabric is treated, dyed, and finished to enhance its softness and durability before being cut and sewn into the final sheet product. Quality control ensures that the sheets meet standards for comfort and longevity.
