How to work a folded hem neckline collar on a sweater

In this video, I demonstrate how to work a folded neckline - a folded hem collar - on my Quadruple sweater. I use a spare needle to pick up stitches around the base of the collar. I then join the picked up stitches to the collar stitches with a three-needle bind off. I also demonstrate how to create a more flexible join by working an elastic bind off with the three-needle bind off.
