Orphan date December 2009 A tortillon IPAc en icon t r t i j n or blending stump is a cylindrical drawing tool, tapered at the ends and usually made of rolled paper, used by artists to smudge or blend marks made with charcoal , Cont crayon , pencil or other drawing media. A blending Stump drawing stump is similar to a tortillon but is longer, more tightly wrapped, and pointed at both ends. Tortillons produce slightly different textures than stumps when blending, and they also are hollow, as opposed to stumps being solid. Cleaning of tortillons and stumps usually involves removing the used outer layer of paper by scraping or rubbing the implement on an abrasive surface, such as sandpaper, carpet, pink rubber erasers, or an emery board .
