I bought a sweater last year and within a few washes it looked like it was 10 years old. I still wear it, but lately I've been thinking that I see nicer stuff at Goodwill. At least that was the case until I was introduced to the sweater shaver. I did one side and you can see the huge difference it made. I've been doing all my sweaters, wool socks, the lining in my jacket. Maybe slightly obsessed, but it just works so darn good.
