The pattern overlay works, but it's more work. I would be nice to have a generator that could create:
Checker & Brick pattern | Allowing foreground and background color, box x:y size and box x:y offset, and possible rounded corners. Alternatively offset could become a border with border color.
Grid Generator | (i.e. Graph Paper ) Allowing foreground and background color, box x:y size and box x:y offset. a Dot, Hex (Polygon), and Triangle, grid would be help full.
