I did find the yarn. It's been discontinued for a number of years. Go to yarndex.com and click cotton, Rowan, and bulky. You can click on the yarn photo to enlarge it. That's what the yarn looked like. You might be able to find something similar, but not in cotton.
No, I think you would still end up with a nice cardigan if you got the same number of stitches per inch as the gauge calls for. That's the wonder of knitting--every creation is going to be unique--even if you were using exactly the same yarn called for in the pattern.
