This is Forecast from Knitty which I didn't like at first but when I saw this version I thought I've just got the yarn that needs recycling for this. First it was used in Remembering Honey, then it became Grace and now it's become Forecast which I think will be it's last incarnation. I could have done with an another inch on the body but I'm all out of yarn but as it's 100% cotton I'm expecting it to fall once I've washed and blocked it.
Now I've just saw another one with shaped sleeves and I'm liking that as well.
