bdpq pattern for Paris ground

[veronika]

To get vertical and horizontal mirror reflections in a hexagon, the top and bottom stitches should be reflections of each other (in a horizontal mirror) and each of these stitches should have internal reflection in a vertical mirror, like W and M (where you will have to imagine the M is drawn like an inverted W).

    W
b        d
p        q
    M

You can change any stitch to have internal reflection in a vertical mirror by replacing all occurrences of L or R with T. So for example, here are the diagrams for "b = clcr": pattern. Note that to get M and W, I had to make the base pattern twice as tall.
