Basically, you paint your watercolours onto wet paper and as the paper dries, the paint mixes and creates beautiful unique patterns. The number of colours you use for this technique is up to you, try using 2 or 3 to start.
1. First, mix your paint in your palette (use your palette tin lid). Remember to test your colours on scrap paper to make sure they are dark enough.
2. Next, tape your paper down (use masking tape if you vae it) This helps to keep the paper from sliding all over when painting and creates a nice border around the finished painting.
3. Using a brush, paint your entire paper with clean water. You don’t want the paper to be soaking if you find it too wet, you can dab it with some kitchen towel.
4. Start to paint your paper, using one color at a time. Experiment with painting in different ways like dabbing the paint on or painting in long brushstrokes across their paper. Try not to mix the paint together on their paper or the colours will get 'muddy'. Remember to wash the brush in between colours. As the paint dries, the colours will mix together and create beautiful and unique patterns.
