When the rest of the group learning with me moved onto purling, I stuck with knitting for quite a bit longer, as I just didn’t quite get it, either.
I’m gonna 'splain it to you, just in case hearing it one more way might help it click. You might consider going to your local yarn store or finding someone to actually show you how to do it…it’s MUCH easier than even a video.
First, bring your yarn to the fron of your work between your needles. The yarn will be resting on top of your right-hand needle instead of coming from behind it.
Then, take that right needle and put it into the first stitch on the left needle…but from the top instead of underneath. Sort of like “scooping” the stitch up. Your needles will be crossed with the right needle over the left, sticking into the top of the stitch.
Then take your working yarn between the needles and around the right needle (you’re going counterclockwise --over the top, on the side away from you, and ending up coming underneath the right needle) and pull the wrapped yarn (new stitch) under the stitch on the left needle and slide the old stitch off.
Probably doesn’t make any more sense just reading it. I know my initial problem with purling was wrapping the yarn backwards.
But don’t be discouraged…it WILL come if you keep at it!
