Installing Shelves in Housing

[Paloverde]

Is there a crafted recipe for shelves? I am seeking something like a board, maybe with braces on the bottom, that one would affix to the wall and subsequently place items upon.

I had not seen this option previously, but this makes a nice large shelf. Just what I wanted.

Fine Wood Carved Pew - Wood Furniture Base (2), Wood Furniture Leg (2), Bonding Agent, Polish, Decorations - Trivial 188

I rotate the pew so that the back is the shelf and the seat is embedded in the wall.

You can also take a table that has a larger top than the base and sink it into the wall so only the top of the table is sticking out. Some tables have perfect legs that look like supports when sunk into the wall.
