How to Create a Plumb Line

Learn how to properly create a plumb line and hang your wallpaper or mural straight on your wall.

Create a Plumb Line

If hanging on all 4 walls, start in the most inconspicuous corner (back corner, behind a door, or behind a large piece of furniture).
Measure from the corner of the wall the width of the paper minus 1/2 inch and mark with a pencil.
Place a level at the mark and draw a straight, vertical line (plumb line).
Create another plumb line every time you reach a corner or start a new wall.
