This is a great skill-building design. Skills are aquired through repetition, which teaches our hands and minds. This doesn't mean that a skill-building design is, therefore, boring to knit or wear! This design keeps your attention, even through the repeats.
The main techniques used are exterior cable shaping, lifted increases and bobbles. Other techniques include Long Tail CO in purl and cabling without a needle.
I knit two long scarves, to wear alone or together, in Cascade Yarns Eco Peruvian wool yarn.
