This pack of Paper Stumps is perfect for smoothing and blending large areas of pastel or charcoal. Made of tightly rolled paper, the stumps come in three sizes, which will enable you to work on different areas of your work. You can sharpen and clean your stumps when necessary. These tools achieve such seamless blending effect that many artists consider these invaluable when drawing human skin, sky and other areas of the art piece that require a photo-like smoothness. The stumps are highly versatile. They can be used dirty, covered in your medium for halftones, shadowing and easy-to-erase soft lines; clean stumps are used for gradual lightening and blending.
