This is one of my favorite sweaters and I will knit it again. The pattern is easy to follow and it would be so easy to add a cable or two to it! Go for it!
This is a very easy sweater to knit. Even the neckline is easy by simply following the exceptionally clear instructions. I have used a couple of KP&S patterns now and find them easy to follow and the finished product something of which one can be proud.
