The pic to the left of Catcott Crossing Halt, shows the attack of the hanging basket liner earlier today. It will be trimmed, using small scissors and a vacuum cleaner to make it stand up. It will then be sprayed (a brush will be used upder the platform) very lightly with a highly diluted PVA/yellowy/browny/greeny emulsion mix using a toothbrush. Then, with an old vacuum cleaner it will be vacuumed again whilst wet to make sure the grass is still as upright as possible. The grass under the flatform will be left messy, the grass at the rear will be trimmed more so it looks less like the mower has been emptied. The glue/paint mix ultimately sets hard and stops the shreds of hanging basket liner breaking off and going everywhere it shouldn't.
The courser ballast is sand from the Solent strained through a fine sieve, something I've been using for years (Combwich). I did a test section the other night with some Green Scenes stuff but it didn't look right, it looking like old tea leaves in colour once dry. The beach sand is tiny pebbles, being almost round, the grains literally roll into place. It also takes PVA well too, in fact alot better than granite or whatever it is that the scenery suppliers give us.
