Yes I have washed mine. You have to wash them carefully. Do not use hot water or too much soap, do not rub or handle roughly. Rinse carefully, press water out with hands, and blot to dry with a clean towel then dry flat. I have never had a problem. I think they actually turn out fluffier and nicer smelling if you wash them.
I have too, the same way as Toria did. Don`t "overstretch" the arms, when you lay it flat to dry, other than that it`s really as simple as it sounds.
I wash my cashmere sweaters in the washing machine all the time. I use the most gentle setting (silk on my machine) and set the temperature to cold and turn the spin off. When they're done, I'll turn the dial to spin and turn it on the most gentle spin and let them go around a few times and then stop it just so they're not soaking wet. Then I'll take them out and stretch a bit to the shape I want and then lay flat to dry on a drying rack (inside out). And I use gentle liquid soap. I've never had any problems doing this.
And I agree with Toria, they come out better than if they were dry cleaned. They are softer and fluffier. Also you have a bit of give, so if you think a sweater is too short etc you can stretch it out to what you want! It's great.
So you shouldn't have any problems, good luck!
Also here's a good guide from where I get most of my cashmere:

I think what they say about avoiding fabric softener is right, I have used it in the past and find that they come out better without it.
I have. I use woolite fabric wash and cold water. I fill my bathroom sink and add the soap then swirl. I add the sweater and leave it to soak for about 15 mins. I come back work on the armpits a bit them drain the water. I fill the sink again with cold and add fabric softener and let it soak just a couple mins. I drain it and squeeze out extra water them lay it to dry on a towel. I reshape it a little and leave it alone.
I have a sweater that I'm over that recently I put in my washer on hand wash. I have whirlpool front loaders. I used woolite and softener and it came out just fine. I definitely agree that washing yourself makes the sweaters much more fluffy and less flat. If you like your sweaters crisp then you may not like how fluffy they get.
