@solarbear Depending on your specific needs and local options, this might be something a copyshop could whip up for you.

(At least something at #CopyJob it would have been possible, so I'm extrapolating for other copyshops.)

You might need to provide the dot-grid files for printing, but I think there are templates for that out there. (Worst case I could also whip up some quick layout for you.)

Alternatively there is some on etsy, I think.
