I love this yarn, the ball will make a pair of perfectly symetrical socks. If you bare a bit OCD about your socks being a perfect pair, this is great. The yarn knits as a stripe, in the centre of the ball is a white bit that shows where the next sock needs to start to get them perfect.
It is your usual sock blend of 75% wool and 25% nylon. 420m on a 100g ball
