[Update June 18, 2008: This pattern is called Bryher. It's now available on Ravelry, for free.]
Here's a project I just finished. I bought an odd lot skein of Artful Yarns "Portrait" mohair blend and mixed it with a worsted weight merino. I used size 10.5 needles, and realize now that I could have used an even bigger size, because the gauge is still a little tight. But it's not too tight by any means. Just a note for future ref., or for anyone interested in making something like it.
The pattern I stole from an episode of Knitty Gritty, when Lily Chin was on talking about a nine-block baby blanket. She showed us how to make a double-sided cable using k1-p1 rib (otherwise the rest stays the same). Brilliant!
I ran the cable off-center for kicks, and kept it skinny because it's fairly warm here down south and this is mohair, and now I just want cool weather to kick in.
