I've been wearing this pullover quite a lot - surprisingly I quite like the pistachio colour and high neckline (one good thing that has come out of my hair loss and subsequent pixie regrowth is that high necklines actually look okay on me now).
The yarn is a cotton and acrylic blend I got on sale at KnitWorld.
I have been thinking I should be knitting with organic fibres, but knitting yarns are expensive enough as it is. My next knitting project will be from an unraveled cotton/acrylic cardigan I made two summers ago that I never wore. Even if I can't do organic at least I can do re-purposed :-)
