This scarf is knitted in Linen Stitch, using 3-ply yarn that runs 600m per 100 gr.
The pattern offers 2 sizes.
Small: Wingspan of 135cm/53in and a drop of 33cm/13in and takes approx. 510m of yarn (the sample in the photo).
Large: Wingspan of 162cm/64in and a drop of approx. 40cm/16in and takes approx. 850m of yarn.
There is a video demonstration of knitting Linen Stitch and how to make a tassel on my YouTube, The Slow Wardrobe, found HERE.
