The corners are often out of line, which makes it unlikely to take one length
around a bend. Measure the distance from the corner, at the top and bottom of the
last length. Add an extra inch to the widest top / bottom measurement and mark a new
length with a pencil, the required correct width.
Cut the required width length and
paste. Press the paper into the corner and mark it to reach into the corner. Peel
the paper back and cut to allow the length to reach the corner and wrap round the
corner by a very small amount.
Complete the adjacent wall in a similar fashion,
using the cut off length just discarded from the previous length. Any slight break
in pattern in the corner should be negligible.
Extra adhesive may be necessary to
stick the wallpapers together if there is a slight overlap in the corner.
