Scarf Shrug Spike Grey
It is the 2nd edition of PDF, an updated version of the 2015 design.

The shrug consists of two pieces, the left and right half include the shoulder, sleeve, and cuff. What challenges the knitter is the pattern shift from ladders to spikes. Start with ladders combined central spike and gradually increase stitches with multiple spikes, all these figures give the item a trendy look.
