There are some tricks to applying your project if any of the Wallpaper panels cover a portion of wall with a door, window, or fixture:
1. Use a straight edge to push the panel flush against the wall or the obstruction.
2. Use a utility knife to cut away excess material around the object leaving enough material that it hangs just slightly over the obstruction.
3. Use a flathead screwdriver or other flat tool to tuck the excess material behind the obstruction.
