It's possible that I've switched from English to Continental. A while back , in college, the same GF who taught me to crochet also tried to teach me to knit. She must have tried to teach me English style.
I remembered through the following years how to do the knit and purl stitches, but could not for the life of me remember casting on or off. So...no knitting, just crochet.
Then, about five years ago, another GF tried again w/casting on and off. It was like water through a colander: nothing stayed in my brain. So she cast on for me, just to see if I really did know the knit and purl stitches.
I did. That was a relief!
Then, a year ago, I joined a community-service group that knits/crochets items for others. I crocheted sturdily on until, earlier this year, I decided to go for it. I tried again English style, because that's what the current GF uses, and she could demo things for me. It also seemed that many of the on-line videos were English.
I even checked out a book from the library called Kids Knit! (Sarah Bradberry) aimed at approx. middle-school readers. It was, bar none, the BEST book I could have read to get me over the hump of fear and give me a small-enough project to start with (a cat toy). And then...the next week...
Within three days (!) of one another, I found this site and the conversation at the knit/crochet group work session in May turned to the question of knitting styles. Out of the six knitters then present, FOUR OF THEM worked in the Continental style!
I seized my chance. In crochet, I always tension the yarn with my left hand. I had been able to manage the yarn with my right in "knitting" English style, but it never felt natural, easy, or even. With some one-on-one, in-person help, I got much better very fast. I'm still not good, but oh so much better in Continental than ever I was in English style.
So maybe I've switched. Or maybe I just finally found my natural style. At last.
