I enjoyed every minute of making this jumper, and it's one of my favourite handspun / hand knit projects ever.
It's the most ambitious colourwork I've tackled so far (3 colours to some rows). A friend suggested that I try 'pick and throw', one colour in each hand. That worked well, and getting pretty proficient by the end of this.
The pattern is Riddari by Védís Jónsdóttir, my Ravelry project is here.
I'm very grateful to Adam of The Real Shetland Company for sorting me out with real Shetland combed top.
