Perhaps this knitting cable pattern is commonly used. But I will share an example simple knitting cable pattern and very pretty used to make this scarf.
In this project, I used a downwards plait knitting cable. 
You can make a scarf project by combining this cable pattern with any techniques desire.

 Abbreviations used:
- K = knit

3rd row : C6F, K3
