I decided tonight that I didn't want to sort out emerald, or knit the acidic cardigan, or even start a sock. Instead, I wanted to knit a scarf. And, 4 episodes of Stargate later, I have one very heavy charity scarf.
It's two colours because I had 3 balls of the light and 1 ball of the dark. I split one ball of light in half and knitted the ball and a bit, then the dark ball, then the other ball and a bit. I like it though.
