I was looking at the game boards. One has a scattering of sand on it - in retrospect, too much. Some smears of filler would have been a much better way to go. Anyway; both the boards were done with the remains of the black and white kids paint from the big squeezy tubes. So the boards would be the same base colour as most of the scenery (done with much the same paint, ne c'est pas ?).
It's too dark.
I've looked at other boards on other peoples' webpages. And I've considered the lighting in the garage. And the fact that there might not be that much ambient light in November.
They are too dark.
I bought some light grey emulsion from Wickes. I've painted the flat, untextured board. It is now too light. But a wash of greatly thinned down kiddies black paint with a spot of PVA in it will do the trick. The same scheme will also have to be applied to all of the scenery. Oh well. Ho hum.
