The yarn is 70 % Gotland wool, 30 % merino, 100 g/300 m. I used two skeins (600 m) but you can make your scarf longer.

The yarn is available here.

You can experiment with yarns and use something in the similar weight or combine mohair with fingering weight yarn.

The gauge is not relevant, as this is a scarf and you can make it shorter or longer. After washing and blocking the scarf stretched 20 cm in the length.
