Also known as: wrong side, inside, back.
The side of knitted fabric that is not intended to be seen. Some fabrics may be folded (such as a collar on a sweater), in which case the “private side” is the one that is leastvisible. Other fabrics may be designed to have both sides equally visible, such as a reversible scarf, in which case the designer is likely to have defined a term that makes it possible to distinguish between the two sides.
