I am so grateful for all the help you guys can give!
As it stands, I think I still need to practice knitting and purling. I am having a tremendously hard time with ribbing; it doesn't look right at all and I think it's because my purling needs a lot of work.
Instead of the above pattern, which I'll do at a later date, I'm working on a "practice" scarf that will be two knit rows, two purl rows, until I have something that's six feet long. Figure then I'll have something warm and lots and lots of practice!
