How to cover the holes where wood grates are in hardwood floors?
![Shelley](https://cdn-fastly.hometalk.com/media/profile/2021/04/26/374472_1.jpg?size=91x91)
We're finally getting a new furnace and A/C!!! They're not going to use the old (large) cold air returns. I need to find a way to cover the holes where these wood grates are in the hardwood floors. They're about 12" x 12"
