I finished this scarf. That is about all I can tell you about it. I don't remember the yarn I used - Koigu, maybe? I don't remember the needle size.
As for the pattern, I learned it from the Koigu Linen Stitch scarf from Churchmouse Yarns and Teas.
I don't remember much about its knitting, but I know that I like it. And that I should keep better records.
Edited later: Today I found a note about this scarf. The yarn is Socks that Rock, mediumweight (Koigu, indeed, ha). The color is Oceana, and I used 2 skeins. I used a size 6 needle.
I started this scarf when we were in Hawaii.
