I've finished the blanket (or bed scarf if you look through certain catalogues ;o) ). It's not really as big a blanket as I originally wanted but I didn't want to buy any more wool so it's now a snuggly thing for the sofa. Perfect, light-weight, long-enough-for-two. 
It's approx. 80cm wide and over 2 metres in length. I've used 6 balls from the stash (don't know what they were as I was gifted them) and I've bought 2 balls of 100g wool. Both were stylecraft, one was a wool mix (dk) and the other was acrylic (4ply). Worked on a 6mm hook, just trebles. So it's cost me £3.45 altogether - a bargain :o).
