Oh, and...

I remember Charlotte asked me a question in a comment a week back and I never answered.

I checked my copy of the Landscape Shawl and while there's no version of the pattern specifically designed for bulky weight (which LB Homespun is), I suspect you could make the worsted-weight version, using a needle that's "comfortable" for the Homespun (maybe an 11?), and you'd have a shawl that was bigger than (but probably not much bigger than) the worsted-weight size.

If that helps.
