What do add to prop/raise the curtain rod a few inches away from the wall

bedroomcurtain-rail

I am about to install a curtain rod onto the wall. The problem is I want to add a few inches between the curtain and the wall than the default length by the curtain rod.

I wonder if there is any item and what it is called (so I can find it in hardware stores). The item will be between the curtain rod and the wall to add a few inches of distance, plus it should be sturdy but allow a screw to go through. Ideally the shape should be close to the base of the curtain rod to make it looks like the extension, but if is not, it's also fine. Is this called some kind of spacer?

Make a couple of nicely finished wooden blocks.

Can be painted same as the wall or to match / contrast with the support you show.
