Watercolour requires little in the way of equipment – a piece of paper, a few colours, and a couple of brushes – and hence its attraction to so many amateur artists.
The most important of these pieces of equipment, I would suggest, is the quality of the paper. Watercolour is a difficult enough medium to control in the first place, but, no matter how good are your paints and brushes, if you are using poor or inappropriate paper your chances of enjoying the experience or producing a satisfying painting are virtually impossible.
Firstly, ensure you have WATERCOLOUR paper and that it is produced by a recognised name (eg Bockingford, Saunders, Arches)
Watercolour paper comes in many weights, surfaces and degrees of sizing (which is what stops it acting like blotting paper) and I discuss these in other tips which refer to watercolour paper – but it is always worth experimenting with different surfaces/papers. I use several different papers, dependent upon the dimensions of the painting, and the effects I want to achieve.
