From Knitting New Scarves:

Most scarves can be thrown on and wrapped around without any thought about their exact arrangement. This is the only scarf in the book that needs to be worn in a specific way, that is if you want to achieve the shawl collar look as shown at left. To see another way to wear it, see page 89. If you want the rib to hold its shape, I suggest you read “A Few Words About Ribs” on page 8.

Requires 32” US 9 circular needle, and US 9 straight needles.
