You will need just over half a ball of
each yarn, so you make two if you like or you can easily make the scarf longer or shorter by adding/repeating, or omitting two or more blocks.

Coasy and easymade scarf in two different yarns:
Kalinka (100% linnen) from Karin Öberg and Lambada (45% polyamid, 28% bomull, 27% polyester) from Thomas Kvist.
