Obviously this is probably the most suitable method if you are left-handed though as all knitting techniques involve using both hands, many left-handers have no problem with right-handed techniques.
Hold the needle with the stitches on in your right hand. Wrap the yarn around your little finger and then around the index of your left hand.
Hold the other needle in your left hand, holding it from above. The tension will be controlled by your left-hand index finger, so it is important to keep the yarn around it slightly taut.
