Jersey fabric is a type of knit textile made from cotton or a cotton blend. Some common uses for jersey fabric include t-shirts and winter bedding. The fabric is warm, flexible, stretchy, and very insulating, making it a popular choice for the layer worn closest to the body. Jersey also tends to be soft, making it very comfortable. A knitting machine is used to make jersey, since it can create the small, even, close grained stitches associated with jersey fabric. Like many other knit fabrics, jersey fabric has a right side and a wrong side. The right side of the material is marked by a series of very small lines which run vertically, and the wrong side has a horizontal grain. In most cases, a garment made from jersey fabric is sewn with the right side facing out, unless the seamstress is making a deliberate stylistic choice.
