I'm just over a ball of yarn in, and so far so good. As the first part of the cardigan mainly consists of the a stocking stitch, I've been distracting myself with episodes of Mad Men to keep it from becoming boring. I'm absolutely loving the yarn, it is so soft and great to work with. And so far I'm quite happy to report that I haven't made any major errors and my cardigan contains no holes. Let's hope that doesn't change!
PS. I came across a book about unfinished knitting projects today, so I guess if I do get bored and decide to abandon it I can always take a picture of it and send it in to the author, in case she's planning a second volume.
