Watercolour paints are some of the easiest art materials to carry around and paint with on the go. With colours, paper and brushes including a water brush that comes with space in the handle to hold water, you can paint with little to no hassle or mess.

Artist, art educator and workshop organiser Alison Pinto notes that when one is new to the technique, the medium becomes unpredictable.
