Plates repurposed into mosaic on stairs (buy plates at discount/dollar or goodwill stores) This could be really cute for a small stairway- 3 or 4 steps as a highlight!
Mosaic stairs made from broken dishes. How colourful! Great way to lighten up a dark stairway.
These are the back stairs in our year old house. I cut white tiles with a tile saw for the top part of each riser and used broken plates, cups, and tile along with glass gems on the rest. The rope was put up by the previous owner and I gilded it.
Mosiac stairs - would love to do this with stone and the like - each stair different? One with polished stones, with one river rock, one with garden stone, one with sea glass, etc.
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.
