I'm excited to have discovered this book and this KAL. I bought the book in January, after devouring the library's copy.
My first pair are the green Corded Rib socks, which I made in Gjestal Silja Sockegarn using size 4 Inox circular needles. The knitting experience was good--the fit not good. (Apparently I was measurement impaired and thought my 8.5" foot was 9.25" around.) They're warm and great for around the house, but a bit baggy. If I were to make these again I would--obviously--measure correctly, and probably go down a needle size for a less-drapey fabric. (Being nearly a sock novice, I just went with the recommended needle size for this sport-weight yarn.)
I am MUCH happier with the blue socks, pictured here nearly ready to be kitchenered. I am making these with KnitPicks Essential Solid in Dusk using size 2 KnitPicks options circulars. I also learned how to make TWO socks on two circulars--what a blast! These fit like a dream and the color is perfect for wearing with jeans.
Next up? probably the slipstitch rib, or maybe I'll up my learning curve and try the chevron?
Addendum: If you'd like to know more about the technique, see my blog.
