This was how I did the walls of the hut:
-
Cut outline from a shoebox - sandwich 2 layers of cardboard with lots of white glue.
-
Cover both sides with drywall filler, sand level when dry with files and sandpaper.
-
Primer with Krylon sandable grey primer.
-
Apply salt crystals and airbrush over with white acrylic paint. Rub off salt when dry to create chipped paint effect.
-
Soak a paper towel with thinned black acrylic and rub on the white walls to tone them down.
-
Paint the bricks and wash with brown paint for grout.
-
Apply pastel rain streaks.
-
Complete!
