Swirtle cowl is a nice flowing cowl with minimal effort for maximum look.

This cowl has a matching sock pattern (http://www.ravelry.com/patterns/library/swirtle-socks)

Can be worked in semi-solid, solid or even self-striping.

Two sizes are given for those who like their cowl short or those who like them long to be doubled.
