The scarf was made with the same yarn and hook size. I got the pattern from This And That, Armina, and is called Easy Shell scarf. I did make two changes to this pattern. I made the scarf longer, it is 76 inches long. The other change I made was to add two rounds of sc before I added the shell row. I wanted it a bit wider and that worked for me.
I am still working away at my started projects and will post when I have something new to share.
