Bought 5 balls of glittery black yarn from Sophie in London Haberdashery and used just under 1 ball on this with a set of 6mm needles.
Initially I wanted to do it in the round but then saw someone on the tube with a horizontal cable knitted scarf and I really liked the way it sat. The twists are pretty easy to do. I bought a kinky cable needle but you could probably use a big safety pin and just slip the stitches back onto the needle. Ymmv.
