I'm going to try to describe my purling method because of course, I don't do any knitting normally! I knit continental, but I throw with my left hand. When I purl, I actually hold the yarn in front of the work between by index finger and my thumb, with the needle under the other three fingers. I lift the yarn slightly over the right needle and just pull it through. It is very fast. It sounds weird, I know, but the stitches are wrapped correctly and its very speedy.
