I've almost finished the coat back now and here's how it looks:
People will certainly see me coming! But I love the way the colours do different things in the cables and the panels. It's always hard to predict how variegated yarn is going to behave. In this case, I got blocks of colour, because the number of stitches in each panel is not that large. The colours would have been a lot more dispersed and blended, if I'd been knitting right across the width with the one ball.
I really like this pattern done in several different colours too, so I may knit it again that way later on. There are some other gorgeous patterns in this book though - it's hard to know where to start.
