I'm finally done painting my formal dining room. But I am left with bare walls. The room is 15x13. 9' ceilings. Wall color is BM-Wedgewood Grey, ceiling accent color is BM-Atmospheric, trim is white. Chandelier is brushed nickle. I need something on the main large wall as well as between the china cabinet. Should I use a large mirror or artwork? Collage or 1 large piece? Window coverings are being made from my profile picture icon fabric. The fake plant is going, forgot to remove it before pics were taken. What about something on the floor, vase with twigs or something for interest?
