I am awaiting my hand-crank Naumann sewing machine purchased during my trip to Switzerland. My DH arranged for it to be shipped to his office. Anyhow, one of the ladies at his work asked, "Why would anyone want an old machine like that? They can't be very accurate."
When he told me this, I replied that they are very accurate, because they only do one thing, and therefore they do it very well. I guess the outside world doesn't realize that with the attachments that came with those old machines you can do so many different things, buttonholes, ruffles, hems, etc.
