Interesting solution if the house you buy happens to have a solid style staircase and the tear-down and addition of a full-on wrought-iron design would be cost prohibitive. Not that this looks inexpensive, mind you.but it could serve as an alternative.
Add salvaged bits of vintage Wallpaper to stair steps in a cottage home house. For ideas and goods shop at Estate ReSale & ReDesign, Bonita Springs, FL. This would be great for the attic room stairway.
