There isn't a single correct way to hold the needles when you're knitting
so experiment to see what feels comfortable for you. Both hands are used equally so whether you're
left-handed or right-handed the important thing is that the needles and yarn make the
right sequence of movements together, knitting the stitches on the left needle and passing them over
to the right needle. Some people like to hold the yarn in their right hand.
This style of knitting is called Throwing because of the way the right hand
loops the yarn around the needles. It's also known as English knitting.
