avoid pattern overload by resisting the urge to cover every wall of a room in wallpaper. instead paint the adjoining walls a coordinating color. for the best result, paint the adjoining walls first, then paper the prevent paint drips on the wallpaper.
The images here are rarely mine. Many or most are images collected over the years and, consequently, lacking original attribution. If any are yours, please write and tell me and I will be more than happy to give credit where it's due.
