The walls in the house are a mile out....in fact the whole house slopes. I am about to paper a bedroom wall and because of the pattern and the sloping walls it will look skew wiff when hung...am sure it will. Instead of using a plumb and spirit level could I actually put the paper up crooked so that when it's done it doesn't look cock-eyed ? I know the easy solution would be not to use this particular paper but have any of you pros come across this prob and how have you dealt with it? Cheers.
