I made a poncho based on this, and now I want to work a cardigan. I am making a free pattern too, and just putting it up as I go along. The wool is gorgeous and wears very well (see this cardigan).
I love the mixture of colours within the blue… lovely!
NOTE: I have made the poncho and therefore trialed the motifs, HOWEVER, this incorporates my discoveries.

I’m writing this down as I go along, so please be patient!:
