Wallpaper is a kind of material used to cover and decorate the interior walls of homes, offices etc.. it is one aspect of interior decoration. It is usually sold in rolls and is put onto a wall using special chemical and fevicol mixture.
Wallpapers can come plain as "lining paper" (so that it can be painted or used to help cover uneven surfaces and minor wall defects thus giving a better surface), textured, with a regular repeating pattern design, or, much less commonly today, with a single non-repeating large design carried over a set of sheets.
