I start with a slip knot (I KNOW! NO KNOTS IN KNITTING, but it's the only way I can figure out how to get it started!!) Then I make a purl stitch into the slip knot, and then pass it back onto the left needle. Then purl into that stitch, pass it back, etc.
I'd love to know how to do that fancy, elegant method I see where the left hand and fingers have the yarn twined through them and the right hand holds a single needle and everything is done in the palm of the left hand, but I'm just not that co-ordinated!
I think I also knit "wrong" (I KNOW, WRONG is a dirty word around here), but I knit by passing my right-hand needle left-to-right through the front loop of the stitch on the left hand needle.
I should really watch the videos!!!
EDITING HERE: I just watched the videos, and I'm knitting correctly! YEAY! And I learned how to cast on! THANK YOU AMY!
