Customizing: paneled wall (for Wayne Manor)

Looks like I never showed off how I made my paneled wall even though I already had it as background in many figure pictures.

These are long stripes of cardboard, shorter stripes of cardboard and then many little small stripes of cardboard put in between. Fiddly work! But if you had go one stripe over the other the cross section would have looked odd.

At first it looked awful when I painted it with acrylic paint, then I got spray paint and it looks so much better (although a bit darker than I originally had intended)
