Weave affects the way a sheet looks, feels and its overall durability. Plain weaves, such as Percale sheets, have an equal number of vertical and horizontal yarns woven together. Plain weave sheets are known for their longevity and crisp feel. Sateen sheet weaves are woven with more vertical than horizontal yarns. The higher number of vertical threads gives the sheet ultra softness. Twill weaves are yarns that are woven two over and one under to create a diagonal line on one side of the fabric. These linens tend to be soft and tend to hold their shape well. Jacquard and damask are weaves that have intricate patterns.
