Staircase Plans

Our stairs have been unfinished since we moved into our house. They aren't really that high on the priority list. But I use them daily and am annoyed at the state they are in every time I use them.

So I did a little painting. When we primed and painted our walls there was still some old, stinky carpet covering the staircase. I removed it shortly after that. This left a gap where the sides of the stairs were not painted.
Here is the history of our staircase in photos.

Here are my plans:

Prime and paint along the sides of stairs- white
Buy pine stair treads- stain, seal(same as floors) and install
Either buy stair risers or try to use existing plywood- paint an hombre effect

Like this and a very similar color.

Also-
Paint hand rail black (same color as doors)
And try to do a family photo like this. (but smaller)

So far I've only worked on some of the painting. Lots to do!
Thanks for looking!
