Back to the trestle
It seemed a good idea (before I started !) to cover the woodwork before painting the plaster. Maybe a bit of cling film would do the job, but no it didn't and it turned into a major operation with paper, masking tape, cooking foil and cling film.
The result so far - I was aiming for a light brownish grey for the rock and I've fiddled about with it for days, washes, sprays, dry brushing, lighter, darker, highlighting the top edges in white, etc, etc, and I still think it needs a bit more brown.
The ground cover will be a sandy brown colour representing dirt and scree and when that's in place I might have another fiddle with the colour of the rock. Grass will be minimal, just a few clumps here and there, with bushes and spruce trees, the latter mainly at the rear behind the track.
I decided that a photo printed window blind wouldn't work so I've added a hardboard backscene on which I'll paint the scenery, or should I say have a go at painting the scenery.
The backscene sits on two supports sitting on the window sill and fixed to the window frame at each end and there's also another support from the window sill in the centre.
and its fixed at the top with two small clips fixed to the window frame. By removing the clips the backscene can be lifted out clear of the window.
Additional lighting is by two 12v LED bar lights fixed to the window pelmet and this has effectively eliminated the shadow of the trestle on the backscene and put it more appropriately under the trestle.
