So, when my yarn came in, I sat down and knit up the back of the cardigan super quickly.
I'm knitting this in Rowan Calmer (color- Cork) on US 8 needles. I modified the pattern a teensy bit; I'm knitting the largest size because I'm between the two biggest, and I want a loose fitting cardigan. However, this size calls for knitting 19.75" before starting the armhole shaping, which would result in a cardigan reaching five inches below the bottom of my butt. How unflattering! So I started the shaping after 15", and I think I'll be much happier with this length.
I'm working on the sleeves now, so that I can save the fun of the fronts for later, but they're slow going. If I'm lucky, I'll get them done this week.
