Long-tail CO video

[IslandTime]

Hi All - I just watched the long-tail CO video on this site and got a surprise. That's the CO I always use, except I learned it from a friend who held the needles in the left hand and the yarn in the right. The video says that after the CO row you do a purl row (if you're doing stocking st) because this CO method creates a knit row - which counts as the 1st row of your pattern! News to me I've just started a new doll dress and I'm looking at the garter st hem - the row following the CO row does look different on one side, but I never thought anything of it before, just considered that to be the WS Not that it matters I guess, after all there has to be a WS

But - in case it ever does matter - if I'm following somebody else's pattern instead of making up something - since I hold my yarn & needles reversed to the video, would that mean my CO row is a K or a P row?
