Sheet size 297 x 94mm
These sheets were developed for HO (1:87) but are suitable for all scales.
They come as a flexible plastic sheet so can be bent around curves, so could be used as a tunnel liner.
May also be used flat for vertical surfaces or even straight river beds.
For the river, you could use side detail to hide the edges and overlay with a clear plastic sheet to represent the water surface.
The sheet comes tan coloured but can be coloured using acrylic paint. The base colour can be removed by rubbing with thinners.
May be cut with a blade or scissors.
Use double-sided tape or sheet to adhere, with superglue (cyanoacrylate) for any pieces which lift.
Non-repeating pattern so joins need to be disguised.
