Solution:
The above statement is true.Yarn is a thread which is made out of fibres, and knitting is the process in which a single yarn is used to make a piece of fabric. The fabrics are made by interlocking the loops of a single yarn using knitting needles or machines. Once the fabric is knitted, then it is stitched to make various clothes. Socks, sweaters and other items are made by knitting the fabric. In the olden days, knitting was done by our grandmother and mothers, but nowadays, machines are being used.
