A "stairway wall" is the vertical surface that runs alongside a set of stairs. It is the wall that you see and touch as you go up or down the stairs. Full definition
I am in desperate need of some fancy schmancy doo - dads to hang on my bare nakey stairway walls and the gigantic shelf over the stairs so a GC to homegoods is EXACTLY what this girl needs!!! (theinspiredroom.net)
... simply perfect... gallery walls... especially stairway walls... should be eclectic... just like the people in a family... no one's feet hit the stairs in the same way... and no one's walls should be the same... this looks just like your family... not anyone else's... and that is why it is so perfect... blessings laney (theinspiredroom.net)
I want to scrawl whole passages of books on the stairway walls, scripture on the fireplace, psalms on the cupboards, epic poems on the east wall, quotes on pumpkins, rules on the stairs, wear out a pack of Sharpies on the backs of the doors, just writing the truth that I know while I know it still for someday.
