Sennelier soft pastels [colour chart 1]
The manufacturing process of the Sennelier cylindrical pastel does not compress the paste and the pastel dries naturally in open air. The life span of a piece of work is guaranteed by the quality of the pastel. but also by the quality of the substrate. If a lot of overlapping is performed. it is preferable to fix between layers. Avoid. however. fixing the final layer too heavily. as the original tones will be lost.
