This isn't helpful either, but have you seen the PI shawls that some people have made? Those are round and very cool looking.
I have seen some very pretty ones, but I'm intimidated by the shape.
Personally, I think I'd like to make a SQUARE shawl, if I don't try one of the PI ones. (I haven't looked at patterns or anything -- I'm still practicing stitches -- so maybe a lacy square design is difficult to do, but I prefer square scarves over long ones and I figure the same applies to shawls.)
