The scarf has been designed using an interesting combination of basic chevron stitch pattern and puff stitches.

I used one fill cake of Scheepjes whirl. With one cake and five pattern repetitions, I was able to get a stole sized final output.

The pattern is easily customizable to desired dimensions.
Patterns repetitions and stitch multiples are given in the pattern.
