I learned to sew on an electric New Home, but when I got to high school, they had treadles and electrics. I tried the treadles and loved them. Now I have the itch to get one. I have my eye on a beautiful one that is being used as a table for an electric machine. I can't sleep nights thinking about it. I don't think it is for sale.
I like them because you can control them with your feet: make them stop on a dime. And I am into old things.
