Welcome from a N.Dakota newbie :D
So many great ideas and chats here. Does your wife quilt too?
My grandma used a treadle until she was almost 90. Her kids bought her a "new" machine with cams and she HATED it, now I have it (the singer with cams not the treadle ... have had it cleaned and oiled but the leg is broken on the table so havent tried it)
