I am looking for ideas on what to use as a fireback. This will be in a traditional open-front woodburning fireplace. I have looked into "real" cast-iron firebacks from many retailers and found them to be rather expensive. I don't like the look of the newfangled stainless-steel firebacks. Although they are cheaper...it looks like someone just stuck a cookie sheet in there. What do you use? How well does it work? Do people comment on how clever it is to use "that" as a fireback? Any and all ideas are appreciated.
