My Nana tried to teach me to knit when I was somewhere between 10 and 12. English style, if I recall correctly. Our biggest issue was that while she knew how to knit, she had pretty severe arthritis (she'd had it most of her life) and it kept her from ever really knitting well. Her mother (my great-grandmother, who I am named for) was an amazing knitter. My dad still has sweaters she knit for him when he was growing up, and while the wool definitely shows some wear after all these years, they're still so well constructed and all the stitches are so even and neat - I aspire to make similar garments some day! But my Nana, having been diagnosed with juvenile rheumatism, always struggled with knitting, and never really learned how to do it well because it hurt too much. So when she tried to teach me, many moons later, she struggled enough just getting the basics out, so it was a long and somewhat traumatic experience.
I remember eventually getting the hang of the knit stitch, but by the time I'd learned it well enough to have a long scarf (that I'd never use in Florida, to be sure!), holidays were over and she'd returned home, so I never learned to BO. :roflhard:
Eventually all those stitches got frogged and I have no idea what happened to the yarn or the needles. I never saw them again, and bought myself new needles (and yarn) when I decided two years ago that I wanted to learn for real this time. I do know I was very frustrated though, because all the directions I could find online were continental and I remembered using my right hand.
I guess my response isn't really what you needed, but even (re?)learning as an adult, one of my frustrations and successes was in part to doing what felt right and comfortable for me. Hence, I'm a thrower. But as long as the stitches come out right, then I don't think how anyone holds the yarn is really an issue. The popular methods are more of suggestions, aren't they?
