Clean natural/sisal runner on simple painted staircase
Full carpet
Stairway painted out- runner with border adds interest
Contrast and pattern= drama
Dark paint on risers high lights treads
Love ! Still clean look of wood treads and painted risers but with narrow runner for quiet and safety
Or paint risers differs and carpet treads all the same
You could put different carpet on each tread and minimize the stripy look of runner.
Backsplash like tile for stone stair . Just put in here for fun
Subtle
Clearly custom runner but simple but cool
Simple -traditional
