The Lake Effect Scarf worked up beautifully in Rowan Kidsilk Haze. One 25 gram skein produced a 54" (137cm) long scarf that is about 4.5" (11cm) wide. I did not block this scarf as I really loved the gently ruffled edges that resulted from the stitch pattern. But I think you could carefully block and still keep the edge effect.
This is a super easy technique - even if the directions read a bit wonky (cause it's brioche after all). But seriously, once you get the technique of creating the wraps down, it is a very straightforward stitch pattern. See the video of the cascade stitch if you need a visual. In the Lake Effect stitch pattern, the "cascades" line up over each other; in the cascade stitch pattern the "cascades" are staggered, and occur over 4 rows instead of 6.
I'm anxious to try this in other yarns as well.
You'll find the link to the pattern over on the right hand side of the blog - under the Complimentary Pattern heading.

Update - this post shows how to add beads to this design.
