So, we have this large, lighted art niche in our open-concept great room. Approx dimensions are 57"w x 65"h (height measurement is where the arch begins, probably another 8 inches of height to the very middle of the arch). I am at a loss to find something that I like in a size/shape that works. We just painted our fireplace bump out SW Calico, because I have a turquoise obsession. :) In my mind, I see us painting the back of the art niche Calico and finding something in a creamy/ivory color to hang. Open to any ideas! Nothing very ornate or fussy looking.

Any ideas?
