I have a light coming and a 8’ round rug (shown below) coming but I don’t know what to put on the two empty walls (i need to style the shelves as well). What do I put on these walls, what size or shape or grouping? I like don’t the transitional coastal farmhouse vibe. (My dining room is across the hall and is navy and has this lighter blue wall color incorporated in the curtains, just for some background on the flow and color choices)
