Well, nothing, according to my husband. But that's what they always say! I am ready to invest in a new mantel shelf for this fireplace because I have always felt that this mantel shelf is too narrow. Hubby disagrees. I feel as if the mantel shelf should extend flush with the beams to the sides and none of that green wall should be showing. Also, the rest of our space with vaulted ceilings and hard angles, is more modern and this shape mantel looks too traditional. Hoping some pros will comment and settle this debate. Oh, and the TV is on an arm and is not centered because I had just pushed it back, so don't bother to let me know that! I am going to put some type of textured paper on the darker green wall soon, still haven't decided what. So feel free to comment on decor, also, but not TV because that has to stay unfortunately. Thanks in advance for those taking the time to post.
