How to cover a fireplace

Yes, it's a non-working fireplace.

It's a non-working fireplace, or at least, I can't use it as stipulated in the terms of my lease. I also put a flue damper in it so I won't loose cool air in the summer and hot air in the winter. I think it used to be a coal stove fireplace, but like so many old apartments, the stove was taken out.

Re wood, the mantle that is already on the fireplace is wood and I've actually seen a lot of decorative/old coal stove fireplaces made out of wood in old apartments in my neighborhood.

Thanks, she would appreciate the compliment.

Once you paste the wallpaper, is it easy to take off? The fireplace also has these pegs that stick out of the wall. I didn't want the wallpaper to look uneven.
