Using KP#2 CO 80 sts using whatever method you prefer, I just hang the hem and let the carriage do the work, I also didn't use WY for this project, Knit for 120 rows. Bind off the stitches on the bed however you choose, remove the hem from the other end. Seam the two 80 st ends, then fold it in half and sew the seam along the 120 sts.
You will end up with a double-thick cozy neck warmer. It's a little snug on the big guys so you can always add knit rows to make it more comfortable.
Check back soon, I'll be posting pictures of this item
