It sounds like you've got some big projects underway! There are so many options. I'd love to help if I can. What style are you going for?

You have a nice geometric, somewhat masculine look going here. I would play that up. I don't think you need to change the wall or carpet color as they seem to be a nice neutral background. Are they cream? is the purple more plum? and is the blue more of a steel blue/gray? The furniture is chocolate brown? I love the striped pillow on the chair. I would layer a wool steel blue/gray area rug and then play up the blue/plum in the pillows. A wool plaid or blue gray herringbone in a couple of throw pillows (replace a few of the solid color pillows) could help to pull it all together. Kind of like the colors in the picture of this bag. Adding brown leather cording would be a great compliment on the pillows. (Not sure the area rug in front of the TV is adding anything)

If you can't clean up the painted edge, you could always add a 1x3 piece of wood as molding. You can even carry it up to the ceiling to frame that wallpaper. I don't see that paint color in the wallpaper, or maybe it's a lighter version of the flower centers. Maybe stencil on a design using the darker color, or another color from the wallpaper to help tie it together. Then narrow floating shelves or vertical frames or something in the painted areas it you feel you need it. Maybe turn the bed around so the wallpaper is the headboard.

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!
