Knitting Part 2

My last knitting class was on Monday. I think it got the hang of knitting and purling. At some point in the middle of the week I was just stumped on how to purl, but I figured it out and now I totally have it down. I am working on a scarf. It started with 20 stitches and now I am up to 64. I don't know how I added more than 3X the amount of the original stitches but I did. My teachers didn't know either, only that it probably happened when I was learining to purl. I also learned how to do ribbing and how to cast on and bind off. Let the projects begin!
