I've been asked this a few times: Though it's not officially sanctioned or even recommended, I soak my scarves in lukewarm water, wring them dry, then toss into the dryer with a bunch of towels. This felts up the scarf (but it DOES shrink it) and consequently makes the edges all puffy, but extremely soft. Another side effect is that the loose threads weld together and this substantially cuts down on fray, and itch.
