I'm sorry to be repeating what may have been discussed earlier. This season of the show just recently started for me. I was just surprised that the sewing machine was not only being used, but was part of the dialogue in that first episode. It has since continued to be in the story.
I was surprised it wasn't a treadle, or modified from a treadle power to electric. It wouldn't have been that common for the electric machine to be in a cupboard in the laundry hall at this time I don't think. I guess I would not have thought that electricity would be installed much in the servant wing.
Thanks all for the conversations, anyway.
