Maybe a little less than halfway up the back. The colors are really lovely. It has decent hand, too, though it will never be soft and cosy. The Mad Crocheter told me she's heard that people have some problems with Noro being hard and scratchy, maybe I'll write up this pattern and it can adapted to this.
Finally, here's a snap of the Annabel Fox sweater on.
Once the V splits, I have to use two balls of each color to work the pattern and that means 6-10 balls at once. So I carry the whole thing around in the 3'x3' box it was sent in. Not what you would call portable. :)
