Don't try to take a short cut by omitting lining paper, even if your walls look smooth and flat without it. If you hang your lining paper vertically instead of cross-lining it, make sure the edges don't lie in the same place as the edges of your wallpaper. Let the lining paper dry thoroughly before you start hanging your wallpaper.
Once the room has been measured and lined, make sure you have all your tools and equipment ready and in place. Inspect each roll of wallpaper carefully, making sure the design and colours are as required and that there is a sufficient quantity to complete the job. Check that all the rolls of paper are the same shade not only by batch numbers, but also by unwrapping them and visually comparing them, one against the other. Check and then double check your measurements before you cut any wallpaper. Unroll the first roll, design side upwards. Measure and cut the first length remembering to allow extra for trimming purposes.
If the paper has a pattern, place the second length on top of the first when you unroll it and take care to match up the design. Use a pencil and mark 'T' (for top) and 'B' (for bottom) in pencil on the back of each length of patterned paper. Paste and fold the first length, let the adhesive soak a while, and in the meantime measure cut, paste and fold the second length.
Draw a vertical line where the first length of paper is to be hung and work in a clockwise direction round the room.
