Anticipate how you'll need to hang your wallpaper in the designated space, especially if it's patterned. Also, consider where and how the seams fall. "The fewer seams, the better, and mirroring seams on opposite walls create symmetry," says Berwick.

How you proceed to hang your wallpaper on the wall depends on the type of pattern you’re working with. For plains or small repeats, experts suggest starting at the left-hand corner and moving from left to right, however, James recommends a different approach when it comes to larger patterns or murals.
