The idea with this scarf is that you are able to wear it just the way you like: as scarf, tube scarf, poncho or almost like sweater. I used drop stitches, so almost every stitch can be used as a buttonhole. To button up the scarf I used two buttons which are attached together. That way the buttons can be moved anywhere on the scarf.

Pattern is in Finnish and in English, English version is at the bottom of the post.
