How to add one inch crosshair dots to battlemap in GIMP?

[Matrix Sorcica]

As the title says. Fairly new to GIMP. I know how to add the inbuilt grid to maps, but what I'd like was for a way to add a crosshair dot pattern, like the various wilderness tiles from WotC (which I'm sure you know). I can configure the grid in "show grid", but that is only for designing maps etc., and can't be added to the image. Or can it? Is there a way to make the inbuilt grid be crosshairs (black or white), and if not, how do I creat a crosshairs dor grid? 'Thanks.

One option I can think of is to make a pattern with a cross hair at a specific size with the cross hair in the center of the pattern image, save as a pattern, and then pick that pattern on a layer

Thanks- one problem, I don't even know how to make a crosshair pattern. Guess I have some homework to do
