The number one question I get asked is how do I hold the needles.
This is how I hold my 9" circular needle as a person who knits English style. The left needle isn't going to go any where so I just hold the needle lightly in my left hand. My right hand does all the work.
In the very beginning I suggest knitting twice a day for ten minutes and then slowly increasing your time. Don't forget to do some hand stretches too.
