I love the comments and the questions! Mary, a reader, left a comment asking where I got the hurricane lamps on my fireplace. I found them at the Mikasa outlet at Pigeon Forge, Tennessee years ago. I placed them on top of wooden trivets.
Pottery Barn has some great ones here; they are a good bit taller than mine which I think would work even better in that space.
Amazon also has shades that are 14″ tall (the same height as the ones on my fireplace).
