It doesn't matter for drawing paper. The primary challenge any artist painting with pastel colors faces is the right technique to use with different types of pastels. You must keep in mind that pastels are effective on hard surfaces like canvas or burlap. Pastel colors cannot be mixed before their application. Therefore, it can be difficult to alter them once on a surface. Thus, confidence is required to apply pastels on any surface. You can also start with shading with light hands to find the right blend of colors.I accidentally used oil pastels on drawing paper.
Will the oil destroy the paper over time?
