The shawl I am knitting right now is a rectangle. It is called the Cameo Shell Stitch Shawl and the pattern can be found at www.KnittingPatternCentral.com
It is not a difficult pattern to do, runs up quickly and looks nice too. I am using Caron Simply Soft and the shawl drapes well and is very soft and squishy.
Best of luck with your choice.
