Ali offers some helpful hints and tips
It's true, watercolour is one of the most challenging mediums but can also be one of the most rewarding. It is actually more forgiving and changeable than people think. The secret to it is to be brave, throw caution to the wind and just have fun throwing paint and water at the paper.
It's official...it's fine to play!!!

Tip and tilt the paper, give it a shake, marvel at what the paint does with little help from you. Once you begin to understand how it behaves with little interference from the artist you are half way to painting in watercolour. For the other half it's a combination of brush marks and drawing skills.
