I'm a huge Pratchett fan and always tried to determine what the Colour of Magic would be, this is how I see it in my head!

Superwash 75% wool/ 25% nylon sock yarn

100 gram skein approximately 420 metres or 450 yards, enough yarn for a standard adult pair of socks.

Knits on needles 2.00 mm - 2.75mm (US size 0-2)

This yarn has a firm twist, and is soft yet durable because of the addition of nylon.

Superwash, machine washable (warm or cool water only), tumble dry low.
