Add some texture and fun to your watercolor paintings with a bit of splatter. I like to use an old watercolor brush and a wooden ruler.
• Load the brush with thick soupy paint.
• Tap the handle of the brush against a ruler, another paint brush handle.
• Allow the paint to splatter onto your watercolor paper.
• Hold your hands at different angles and levels to vary the pattern.
Practice on a test piece of paper or the mixing tray of your palette. When you get the hang of it add splatter to your watercolor paintings to give it some texture.
If you want to keep splatter off of certain areas of your painting, like the sky, shield it with another piece of paper. This way you can add texture to the ground without having a whole bunch of dots in the sky.
