Thank you guys, for your kind reactions!
Vignette (1)I do not make vignettes for every vehicle, but as I do not like the tracks of this model very much, a vignette can be a good approach to hide them a bit.
First I searched the house for a useful starting point: something round that I could pour some plaster in. Finally I arrived at the upper part of a plastic yoghurt container. For a starter I carefully cut this part off, and sanded the edges a bit.
Made a bottom from a piece of cardboard.
I covered the cardboard disc with plastic kitchen foil as a protective layer against the wet plaster, and sealed the seam with white pva glue.
Drew the outline of the tank, and made a fence from matches and cedar wood for lighting cigars, that is crushed by the tank. In fact it's the summer variant of the Matchbox vignette.
Fluid plaster poured in.
Just before the curing of the plaster I pressed in the tracks of the tank and added crushed parts of the fence, and some stones.
Now to continue with painting, weathering and gardening....
