Get a cow hide rug. Most people think they are high maintenance but they are SO easy to maintain. They can literally be hosed off-- ours is under our kitchen table and all sorts of stuff gets on it. It's a light color and has not been stained even spilling cran grape juice. It wipes right off, is easy to vacuum and is light weight enough for me to take outside and shake off of my own. A wool rug in that size is so much more work.
Adding old-style windows like this would add so much farmhouse character-- unfortunately old windows like this aren't energy efficient and new versions of them are so expensive. I think it could look great to use a window like this in the divider next to the secretary desk btw the kitchen and dining room-- take out the spindles and reframe a window like this.
Sisal carpet is so easy to clean and is cheaper than wood stairs. You can just sweep it off instead of dragging your vacuum and it lasts a long time I also love this railing. Much more secure than what is there now
