Just wanted to share - different finish color

After posting my question about what colors to use on a sign I made, I ran into this.
There were several you-tube videos about this but I had never seen it on this forum.

I wanted to create an old-weathered look on new wood.

The background is a color-sheet for milk paint.
The piece of wood is soft curly maple.
The coloring on the piece of wood is from dissolving some steel-wool in some vinegar.
I used the "stick" to push the steel-wool down into the vinegar on day-two.
The mixture should "brew" for four days before being used according to the videos.

The third picture shows where I sanded through it with some fine sandpaper.
It was deeper than I thought, but not by much.

Interesting finish, not sure what to do with it - maybe use it under a crackle-finish.

I used a half of one steel-wool pad (fine) in a cup of vinegar, most was still not dissolved when I did this.

I'm interested in the out come of the finished sign when you get done, inquiring minds wants to know..... :p
