It can be a very stretchy single knitting, usually light-weight, jersey with one flat side and one piled side. It can also be a double knitted jersey, with less stretch, that 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. The material was firs produced on jersey, Channel Island during medieval times. |
