Wallpaper has been used since before the 18^th century to cover walls and act as a decorative element for interior spaces. It has notably emerged during the Renaissance period as an affordable alternative for tapestries, which were used by the rich classes back then to cover the stone walls, keep away the heat, and give color to their rooms. The earlier wallpaper featured scenes, rather than patterns, and its biggest two manufacturers were England and France. China, also, started manufacturing high-quality wallpaper in the late 17^th century. It was hand painted and costly, and that’s why it was mostly used in palaces.By the arrival of the 20^th century, patterned wallpaper had become an essential wall finishing material for homes; however, halfway through the century, it had lost its popularity to plain painting. Wallpaper may not be what is trending now, but it is still a wall-finishing option worth considering. Manufacturers have recently been recreating wallpaper with some advantageous characteristics like blocking WiFi waves, protecting walls from falling during earthquakes, or for lighting purposes by incorporating LEDs. Also, the wallpaper techniques have evolved from woodblock printing and stenciling to digital printing.
