I am with @cryptocariad ... To my eyes the sweater is an amazing piece of art, but I do not know how much pressure you had making it or if you had a different idea about its appearance. I love the Color combination, the tailored fit and the pattern. I cannot imagine to knit something so complicated.
And with the left over yarn, as I like the colours so much and seldom wear arm warmers, I would knit a sleeveless sweater (I don’t know the right term... in German it would be ‚Pullunder‘)
Thanks @neumannsalva! A Pullunder is a good idea. I pretty much wear wool and layers year round, so it would get a lot of use. I still have the buckets of dye, so if I run out of a certain color, I could dye a little more.
