Wallpaper feels intimidating until you realize most problems are predictable: bad starting lines, underestimated pattern repeat, and rushed cuts around outlets and corners.
The best installs begin with straight reference lines and a clear cut workflow. That alone reduces waste and makes seams disappear in normal room lighting.
If your estimate includes realistic repeat waste and one backup roll, the project becomes creative instead of stressful.
