Jersey is made of wool, cotton, and synthetic fibres. The fabric can be a very stretchy single knitting, usually light-weight, jersey with one flat side and one piled side. When made with a lightweight yarn, this is the fabric most often that is used to make t-shirts. Or it can also be a double knitted jersey, known as the interlock jersey, with less stretch and creates a heavier fabric of two single jerseys knitted together to leave the two flat sides on the outsides of the fabric, with the piles in the middle. Jersey is an excellent fabric to use for draped garments such as women’s tops and dresses.
