Find out how many rolls of wallpaper you need, using our handy online calculator. Make sure if the rolls you buy have the same batch number, so there's no variation in shade.
To make sure everything fits and is straight, you'll need a guide to hang your first piece. Measure 50cm in from the corner, make a pencil mark, then use a spirit level to draw a line to the top of the wall. Align your first strip of paper at the top, following the line down, and leaving a slight overlap at top and side. Cut off at the bottom. Put this strip to one side.
Paste the wall to just past the pencil line. Align your paper at the top, smooth it with a dry brush, getting rid of any bubbles. Trim top and sides neatly. Continue with the next strip, making sure you match the pattern as you go round.
