http://cache.lionbrand.com/cgi-bin/patternFinderLion Brand yarns has many, many free patterns. There is a sign up form that is easy to complete. Lion Brand, also, has a newsletter, that one may op in or not, to be sent to your email address. I like it.
The above scarf was not their suggested yarn, nor sized hook as in the written pattern. I used a 9mm hook. If, your yarn is thinner than the suggested one, just add more chain on your initial row.
What I particularly like about the scarf is, that it fits flat around the neck and then, all that is needed to secure, is to twist the hanging ends around each other.
