In my house, there is a freestanding cast iron stove. But we don’t like it too much, especially it is not safe for kids. So we move it away. On the wall, there is the chimney pipe, diameter 9 1/2 inches, depth 8 1/2 inches. Please see the picture attached. Is there any easy decoration that can hide it? Thanks a lot. BTW, we don’t have plan to remove the chimney.
