Do you love crochet more than knitting?  Here's a cute pattern from Lyon brand yarn.  http://www.lionbrand.com/patterns/90268AD.html?noImages=0&utm_source=20100115_Jan15&utm_medium=Emails&utm_campaign=Weeklynewsletter&utm_content=Preview-CardiffCowl&r=1

This one isn't a moebius, but it could be just by adding one twist before joining the intitial chain.  If you wanted it to be more like a shawl, you could make the chain longer and wider before finishing.  I love the delicate drape to this piece and alpaca yarn is so fabulous to work with and wear.  It's as good as cashmere to me.
