Caveat: when the article mentions the “dominant hand” and “non-dominant hand” they really just mean “right hand” and “left hand”. These knitting styles do not adjust to your personal handedness. So I guess you can read it as written if you’re right-handed, but if you’re left-handed this was not written with you in mind.
I’m left-handed, and for some reason for me personally, Portuguese style has always been easiest to adapt that way. Might just be me though.
