I have started a try to make brick walls with single bricks.
In the first picture you see a first try.
I have printed linies on a paper and clued the bricks along the linie.
In this picture I clued the bricks directly om MDF-woodsheet.
The joints between the bricks I grouted with dry fine quartz sand, cleaned the bricks with a brush and fixed the sand in the joints with matt clear Vallejo-color.
The finally step is to build 3D-brick walls.
Here a first test.
