Arm KNitting has become extremely popular. However, I could never get the concept of it or learn how to achieve this beautiful look. I did find a great crochet pattern on Etsy by Kay Crochet Patterns. The pattern is called Crochet Bulky Rope Scarf.
This pattern can be made with any type of bulky yarn. It works up very quick and is easy to assemble for whatever length you would like your scarf to be.
