Thanks lads
Small update... Using a decorator's spraygun, I sprayed the new board with three layers of earth-coloured emulsion - each coat slightly lighter than the one before, to build up a kind of depth effect...
Next step will be colouring in the rocky areas, then onto weathering and greening, then finally painting in and varnishing the river (important to do this AFTER the application of flock and suchlike, otherwise you get bits sticking to the river surface... Also, once I've added flock, bushes, tufts etc, I will drench the whole lot in a couple of spraycoats of very thinned PVA - like 5% glue, 95% water - to fix everything in place. Obviously don't want to do that over the top of the yacht varnish on the river... )
Anyway, that is to come. For now we have...
