This scarf pattern came out of the book one-skein wonders. The book got the cast-on number wrong (try casting on 20 and you can't even get one cycle of the stitch pattern in! it should be 40). I was using a ball of mohair that I had sitting around, and my gauge was off, so I cast on 28. (The pattern requires y stitches where y=12x+16 for integers x . . . now solve for x when y=20. Yeah.)
The scarf came out a bit short. I blocked it and it's somewhat better, but I don't love it, and I think, in the end, the mohair might be a bit too itchy for right next to my face. So I think I'll donate this one to food and friends or something.
