I am knitting PetiteKnit’s Oslo Hat Mohair edition
After casting on, you knit several inches. Then the pattern instructs you to knit together the next round of stitches and cast on edge together. You essentially pick up a stitch from the cast on edge and knit it together with the associated stitch on the current row.
I am really confused why we would do this? Is this to help with the fold of the hat…?
