In another article, I listed drawing and painting tools and materials. That is one way of classifying creative possibilities. Another way of identifying is by naming drawing and painting techniques and the style in which they are applied.
Techniques, materials, tools, and ways of using them are highly connected. Still, it makes sense to look at and organise them separately, because then we can work in a purposeful way. And we have handles for an artistic view of the work of others.
