Good challenge for a planner to do it!! But first, is your Living room done with the flooring and surface finishes?? Second, Can you please share a pic of your room!!?? it will largely help in understanding!

Hi Raghvendra! What I understand is that you require ideas for cushions and also for the wall. First of all, decide on the theme which you are going for.....modern...European....etc. Your furniture looks a mix of the two. As such a full view of the room would help one to decide on the best combination. Also the furniture material esp sofa will decide the texture of the walls and the cloth you will use for cushions. Also the size of cushion will matter. Personal choice of the color is best. I always go for rustic looks which matches most & mingles with all set ups. It give a look of luxury too. Pl consider all these facts before you decide. Hope this will help you. Looking forward for a happy home!!

How can I redecorate this living room space 10 feet wide and 18 feet long

Nicely arranged. My two cents: Unlike the others I don't recommend a blue carpet. My suggestion is to go for a neutral colour or complimentary colour carpet. You will need a bigger sized carpet than the one you now have. If you look online, there are article that mention how to choose your carpet size. Ideally, the carpet should be big enough so that atleast the front legs of the sofa should be placed on it (you can check online). The corner decor looks crowded. Remove the glass table on the left side. The potted plant and the big blue pottery jar can be placed down together with a second green plant that is smaller in length than the pottery. Place them where the glass table is now present. For the corner space: place the smaller pottery together with the red tea light Holder. You can also place another green plant there.
