I moved the curtain rod in the school room up as high as I could. This lets in a little more light, and makes the windows look taller. It didn't take long, either.
Last weekend I made more things to go on the walls: a paper twist from an off-white paper sample for the dining room, and a chain of three small wire wreaths to go in the bathroom.
A while back, while I was looking in the scrap pile for wood to make a shoe rack for the coat closet, I found an old crate that we weren't using that was just the right size.
I used leftover tablecloth fabric from making skirts to make pockets for some of my other skirts; simple bags sewn to the inside of the waistbands. I'm not a purse person.
I salvaged a simple Ikea lamp that my husband was going to throw away, and I'm in the process of painting and rewiring it; I found a new cord (with socket) at the Habitat for Humanity ReStore for $3. When it's finished. it will go in the school room, which only has an overhead fixture at the moment.
