One of the boys' merino sweaters got into the washing machine recently, got caught between the washer and dryer and laid out flat to dry. Didn't matter, it's been several years since he could wear something that size now.
I am very careful with my wool stuff. Some of it can go through the washer (mostly long underwear and socks) and other stuff can't. I've had watch caps you could do anything with, no problem. Others I've hand washed in cold water with mild soap, laid out flat to dry and they've never been the same. Never know. Filson coats, Filson and Pendleton wool shirts....those all go to the dry cleaner, no ifs ands or buts.
