Finally, we get our watercolours out - and this is where we are setting the groundwork for 'Advancing Tone, Value and Colour', the second instalment of the Sketch Loose course.

Flowing colours is all about the water - and today we will look at exactly why water is so important.

The aims of this challenge are...

1. To understand why water is important in watercolours

2. To look at wet-on-wet vs wet-on-dry techniques

3. Create some loose watercolour textures

4. Have fun with an abstract sketch
