With more than 25 years of experience I have hung a wide range of wallpapers including wide paper, hand prints, natural fibres, vinyl’s and wall murals. Patterned wallpapers are designed so that the pattern "repeats", and thus pieces cut from the same roll can be hung next to each other so as to continue the pattern without it being easy to see where the join between two pieces occurs. In the case of large complex patterns of images this is normally achieved by starting the second piece halfway into the length of the repeat, so that if the pattern going down the roll repeats after 60 centimetres, the next piece sideways is cut from the roll to begin 30 centimetres down the pattern from the first. The number of times the pattern repeats horizontally across a roll does not matter for this purpose. A single pattern can be issued in several different colourways.
