The watermill walls cutted in cardboard and balsa beams glued were the wood supports should be. I create bricks from colored plaster and I built the walls between the wood supports. More plaster filled the sims and the section walls were ready.
The base took shape with Dow blocks and some paper tissue for a solid base to work on. White glue covered everything and sand and small stones sparkled over the entire base. The stone bridge and wall are made of plasterboard with with sculpted details. Bridge floor came from commercial mold .The rocks are natural stones in a very fine shape.
