Can you post a link to the pattern or even the pattern name?
It sounds like maybe you knit the hood and then pick up sts around the edge (framing the face) and knit a ribbing. The edges of that ribbing would then be overlapped and sewn down to the 14st space in the front. Sew one side of the ribbing down and then stitch the second side on top of that. This is all a bit of guesswork however.
