This how-to video demonstrates the purl stitch using the continental method, or with the left hand. Start with the yarn in left hand. The middle finger (or index finger) is used to push the yarn down and to the right, to where the right needle can easily push it back through the stitch. This method requires the fewest hand movements of any purl method, and is consequently the fastest (with the exception, perhaps, of the "Combined Knitting Method" of purling). This method of purling, when combined with Continental Knitting, makes for a very fast ribbing. Watch this video knitting tutorial and learn how to knit the purl stitch.
