This was how I wanted the shelves of bottles and jars to look like, and seeing it against a type of stone solidifies my opinion that that would look nice. I also think that the bookshelf should should be a group of shelves as well.
With wood really, you don't want to take anything away from it.. So when furnishing a magnificent room like this one, you want to stay away from any bold pieces that would destruct the attention from every detail of the architecture! Loooove the room!!
