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.

Have you ever thought about floating shelves? I think pairing a few floating shelves together would look great and would free up space in your living room. I really like the Eugene floating shelf from Bryght and I think it would compliment your existing pieces. http://www.bryght.com/product/160/eugene-cocoa-shelf

A new fiberglass or wood door with lots more glass in the panel. It will brighten that hallway up considerably.If you are concerned about security, use a door with glass and a decorative grill on the exterior. www.glass craft.net.

Hi Nisha, Like the way you have chosen a neutral colour palette keeping in mind the size of your Living room. Would like to share a simple home styling tip: Always slip your carpet below the 2 front legs of the furniture around it. This helps to pull the room together. Your wall can be treated in multiple ways: It's a nice idea of having a floating shelf. This can also be combined with a collage of frames, small wall art, Some Letters, Arrows, etc. around it to fill the wall as seen below: Regarding the painting idea: Choose the subject as an abstract/geometrical, since this would match the style of your living room. And always hang the painting with its base at just 6-8" from the sofa backrest. (keeping them at an eye level). A) You can opt for a huge landscape framed painting, that would cover the wall. OR B) Have 2 similar vertical frames, hung side by side. Can also add a focus light above to highlight these paintings. You can highlight it with a wallpaper / textured paint finish (only if it is continuous wall) in the family of neutral shades and geometric patterns. Also can have a huge wall art or a figurine hung on the wall. These are easily available online. Colour Ur Blank Spaces is an online interior design service.
