Hi,
The second site you posted was very interesting. The first e-mail was about what I would call a curtain stretcher. It is a frame with hundreds of nails sticking up around the edges. My mother used to have one. You stretch lace curtains on it to dry. That way they are stiff and don't need ironing. I remember helping her do it when I was a kid. I am sure some of you remember the metal frames that you put a man's dress pants into when you hung them to dry. My Dad didn't wear dress clothes to work but one of our neighbors always hung her husband's pants out like that.
