Thanks jessie for the good recommendation. I just bought my wallpaper at sipario gallery. It only cost me $1400 for 5 rolls of wallpaper. Previously i went to other shop, they quoted me $2000 for 5 rolls. Luckily i went to this shop and see. Their range of wallpaper is bigger than them also. The salesman is also very polite and patience. I believe he is really a specialist. He explain to me a lot of things which is very important. I'm very happy with the job done and it really look great after installing my wallpaper.
