finally weekend and time for some more building options. The tile actually took another brighter coat of green which matches more to the flock I currently own.
After another night of drying out I finally put PVA glue on the wood and carefully sprinkled some green flock on it. The result is what I expected it to be. As the coat of flock is not that thick (need to safe money on that) the basecolour shines through a bit. That doesnt matter that much.
Finished by now:
1) Rural road (glued, painted, drybrushed, ready)
2) Rest of the board (2 times basecoated, 1 time coloured, PVA glued and flocked)
