Right - I'm not doing this in the Rowan Polar because it is too thick and heavy ... I would be doing weight-training everytime I wore the scarf I think!
So I have some black & cream yarn which is really soft (cashmere, extra fine merino and silk) and I am going to use that instead because I don't have enough money at the moment to go and buy new stash.
OK people - for those of you doing 2 colours .... see my experiment below - I personally wouldn't do colour 1 / colour 2 / colour 1 / colour 2 / colour 1 / colour 2 because when you weave I don't think it would work well - you may like the effect - in which case, please ignore me!
I am going to do 4 strands in one colour (1,3,4 & 6) and 2 in the other (2 & 5).
I hope to co for this tonight

(I spent ALL last night untangling the cream yarn which had got into a mess for some reason)
