I have a couple of merino wool sweaters that say "dry clean" on the care tag. However, I've read that cashmere and other wool fabrications can be handwashed (or in my case, washed in the washer on the "hand wash" cycle). In fact, I've read that it's actually not as hard on the fabric as dry cleaning is. Does anyone have any experience with this? I'd really hate to ruin a sweater . . .
