I have seen some crafting instructors, in particular video crochet instructors who include left and right handed versions. For crochet it makes sense because it is a strongly handed craft as which hand holds the hook affects the direction of stitches, etc.
For knotting, a vast majority of the instructions you see in books have no hands in them at all. If it's a step by step instruction set, there may be no hands, but the dominant hand of the instructor definitely has an effect. In videos, though, you can emphatically see handedness, and if you're a visual/kinaesthetic learner that might trip you up?
