How about this pretty cashmere? The Cashmere Queen is a merino/cashmere/silk blend from Schoppel. This cool yarn is just as soft as you'd expect, but with a really cool almost-felted texture that Schoppel does so well.
Sally is using two balls to create the Purl Bee Lovely Ribbed Cowl in a super simple 2x2 rib. She will block this out aggressively to flatten out the rib a bit and create a nice drape.
I was also smitten with this pretty Fields of Wheat cowl I found on Ravelry. It looks like the knitter did fewer repeats than the original (free) pattern calls for, so she was able to get a nice length with one ball.
