Knitten in brioche stitch. about 2 metres long.
Somewhere at the end i knit a hole in it so i can pull my scarf through it so it wont unfold. Just don't 'knit' the place where you want the hole, so that it's like 2 seperate scarfs you doing. when the hole is long enough(it'll stretch) you just knit like you were doing.
AT the ends i put some pieces of the same wool i used.
