1 The rivers and streams are made from independent modules or pieces of several shapes: straight, curves... Almost every riverine system can be built
2 The widht can vary but it must be the same in the piece-ends. For streams the end-widht is 2.5 cm (1") and for rivers 5.0 dm (2"). The lenghtis indifferent
3 The base is made from 2mm cardboard. The shapes are traced on it with a pen. For streams one cardboard layer is sufficient, but for rivers I use three, glued with whiteglue
4 For streams the borders are made with LITEPLAST. The paste is placed with a small trowel and the fingers (wash immediately after!)
5 For rivers the borders are made from plasticine covered with several layers of white-glue (let dry between applications) to harden it
6 The borders are covered with a generous layer of white glue and then sand is sprinkled over to texture it. Afetr dry the borders are painted with brown or green acrylics
7 The river bed is made with a layer of LITEPLAST that is humidified to give it a water-like texture. In the case of streams the river bed is not neccesary
8 The beds are painted with acrylics using two basic colors: dark green, near the borders, and dark blue towards the center. In the case of rivers, an additional central strip of black paint can be neccesary. Use a different paintbrush for each color. Inmediately mix the colors in the contact zones to achieve  transition zones green-blue(-black)
9 The final result will simulate the reflexion of the river borders (usually green) and a smooth transition towards the deeper zones of the river bed. After drying, paint over with acryclics varnish aplying several layers if neccesary
10 The borders are decorated using green sawdust, lichen, stones (cat liter) ....
11 The elements are placed onto the table fixing them with pins
