I love this show - I watch for free online at the PBS site - I just wait until Monday and I can watch it for free. Yes, I did see the sewing machine - Maybe Lady Grantham loaned it to her for the curtains. I can't believe there is only one more episode - I wish it would just keep going.
By the way, I found this really funny show on Netflix - its a BBC show called "Keeping up Appearances" - if you want a good laugh - you will love this. I relate to the characters because I once had a neighbor like Hyacinth - check it out.
