The person who wears this has worn it nearly daily (in the winter) since he received it, and it’s still as good as new. Seriously. I wrote to Brown Sheep and complained that their yarn is too durable.

Photos were taken in 2014, so 16 years after the scarf was knitted.

The color orders in the stripes of this scarf form the group S_3; think of S_3 as acting on the triple (green, grey, black).
