This cowl is so incredibly easy - all you need to know is chain and half double crochet! It's the perfect project for a beginner, or an easy, mindless one for a more advanced crocheter. The size can be easily adjusted by increasing or decreasing the number of chains you begin with, or the number of half double crochet rows.
The pattern is available at my blog as well: http://jaysboutiqueblog.blogspot.com/2012/04/free-pattern-easy-twisted-cowl.html
I also sell the finished project at my etsy store here: http://www.etsy.com/listing/97136564/custom-twisted-cowl
Gauge not necessary for this project.
I learned how to crochet years ago, but re-discovered my love for it last December. Since then, I have been hooking like crazy whenever I can find time!
