While I was staying at the hospital with Katy, Yuki H. shared some of her good cooking with me and gave me a good tip for keeping our house warm. She suggested that I put bubble wrap on the windows!
When I got home, I tried it. Now, the room is much less drafty and there isn't so much water on the glass. It is a great idea. Yuki H. is very smart. Thank you!
If you are renting a place with single-pane glass, I recommend you try it. The bubble wrap was pretty cheap at the hardware store.
