If there is a prominent pattern, matching the pattern can mean quite long ends
going to waste. Make sure that enough wallpaper is bought to complete the job.
When buying the rolls, check that they come from the same batch, to avoid slight
colour variations.
If you are planning to hang the wallpaper immediately, it is
often possible to buy another roll from the same batch if required. Be careful
though, as running out of paper could prove disastrous.
