History time: The Chinese invented paper in A.D. 105, but it wasn't introduced to the Western world until 1490 when England became acquainted with it and put it on walls.
Then artists were commissioned by the wealthy to paint designs on small sheets of paper, 22 inches by 30 inches in size. The hand-painted sheets were then fashioned together for a complete pattern-matched design for the wall.Today's wallpapers generally measure about 27 inches wide by 11 feet long and 90 percent of the time they are printed out by machine. There are still hand-painted papers available. And though more expensive than the mass-produced version, they are still somewhat affordable.
By the 18th century, paper for walls became an acceptable change from wood panels and wall tapestry. It was in 1785 that the first wallpaper printing machine was invented by Christopher-Phillippe Oberkamph. The machine for the manufacturing of endless rolls was designed later by Louis Robert.
The variety of categories of wallpaper seems endless. Florals appear to be the most popular; perhaps because they remind us of nature's gifts. We know that geometrics combine lines, curves and swirls, and these papers are experiencing great public acceptance right now.
