This pattern is intended to be an ADD-ON, not a full standalone pattern; the overall construction is based on the Concertina Cowl (available in my store).

This design is a cosmetic variation, and this pattern gives instructions for the stitch textures and garment shape, but not the pleat technique which is necessary for forming the back section.

The pleat technique is detailed in the original pattern here:
