wow, Nikki! You're learning a lot faster than most of my new knitting students! Congratulate yourself!
The purl stitch is the inverse, or inside out, kind of, of the knit stitch.
Watch the video in this forum about purl stitches, and I recommend the German method. (don't worry, when you clik on the purple tab above, you'll see how to look at the purl video)
What you do, is, take your needle, and come in thru the front of the stitch, and then wrap the yarn around the needle, in front.
You know how you made an X with the needle, and then wrapped the yarn around the back, and then down thru the middle, of the X, to do a knit stitch?
Well, instead of going thru to the back, just push your needle tip thru the front of the stitch.
Watch the video. If I was there in person, I'm sure I could show you. You sound like such a smart person! :yay: The video, the German purl method, is what I'm trying to explain. You can pause the video, too, which helps the mind grasp the concept presented.
