I didn't realize it was a faux stone pattern. There is nothing you can do to hide the grid pattern I am afraid...However, as it is recessed in a niche, I am inspired by your windchime pattern to think of adding eyelet hooks on the top and bottom that align with the vertical grids and uplight them from behind...This idea but with less vertical rods, and then uplit to give an effect like the second picture...

I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

Keya, glad you decided to take the one reader's idea about moving the armoires in front of windows that you don't need and giving the bed a wall of its own! And, yes, you can have Roman shades on one wall and layered drapes on the other. When I had drapes made for my tall sitting room windows/doors, I had them use the same fabric for the Roman shades for the smaller windows on the other wall. For me personally, in these older Indian homes with all the odd nooks and niches in the walls, perhaps it would be more soothing to have a light/med tone paint on the walls that blends with the drapes/blinds for an 'uninterrupted' look, and I would use the same color on ceiling and beams. (but that is just my thought) I would start the process with a large carpet with your favorite colors, then choose your Bedcover & cushions, then your wall paint and fabric for drapes/blinds ..Not certain what style you like, but if you really like a particular Ethnic bedcover fabric, you can always have them stitched into curtains or Roman shades too. Can't wait to see the "After" pics!

I have no idea we need pictures
