A stump, or tortillon, is a rolled paper tool used to blend charcoal, graphite, and pastel. Learn the difference between stumps and tortillons, how to use them, and why they give artists precise control over tonal transitions.
You can blend charcoal with your finger. It works. It is what cave artists did, what Renaissance apprentices did, and what most beginners do when they first pick up a stick of charcoal. But your finger is wide, imprecise, and covered in oil that can stain the paper. When an artist needs to blend a shadow the size of a fingernail, or soften a transition between two tones in a narrow area, a finger will not do. That is what the stump is for. A stump is a tightly rolled cylinder of paper, pointed at one or both ends, that an artist holds like a pencil and uses to push dry drawing material across the surface of the paper with controlled precision.
A stump, also called a blending stump or tortillon, is a drawing tool made from tightly rolled or compressed paper, tapered to a point, used for blending and smudging dry drawing media such as charcoal, graphite, pastel, and Conte crayon. The name "tortillon" comes from the French "tortiller," meaning "something twisted." Stumps and tortillons are similar tools with a few key differences in construction and performance. They are inexpensive, widely available, and essential for artists who work in dry media.
This entry covers what stumps and tortillons are, the difference between them, their history, how to use them, and how to maintain them.
A blending stump works by picking up dry drawing material from the paper's surface and redistributing it. When an artist draws with charcoal or graphite, the material sits on and between the paper fibers. When a stump is rubbed across that material, the paper fibers of the stump grab the charcoal or graphite particles and drag them across the surface, smoothing out harsh lines and creating gradual tonal transitions. The stump does not add material. It moves what is already there.
The LiveAbout guide to blending stumps describes the tool as "a small roll of tightly twisted paper preferred by artists for precise blending. It gives you more control of your drawing and allows you to soften lines or smudge shaded areas as you see fit."
The pointed tip of a stump allows for blending in small, specific areas. You can soften the transition between a shadow and a highlight on a portrait nose, blend the tonal gradient of a sphere, or smooth the texture of skin in a figure drawing, all with a tool that is as precise as the pencil that made the original marks. The side of the stump can be used for broader blending, and the flat of the tip can be used to push material into larger areas.
Stumps and tortillons are often used interchangeably, but they are different tools with different construction and performance. The Improve Drawing guide explains the distinction:
Blending stumps are made from compressed paper pulp, formed into a solid stick with a point at each end. They are softer, denser, and have a velvety surface texture that allows for smoother, more subtle blending. Stumps are more expensive than tortillons but last longer. They can be cleaned with a kneaded eraser and reshaped with sandpaper. Because they are solid, they hold their shape under pressure and give the artist more control.
Tortillons are made from sheets of paper tightly wound into a cylinder, tapered at one end. They are hollow, harder, and less expensive than stumps. Tortillons produce slightly different textures when blending, with a harder, scratchier feel. They wear out more quickly and are typically discarded when they become saturated with drawing material. However, they are cheap enough that an artist can buy a dozen for the price of a single stump. The Wikipedia article on tortillons notes that tortillons are hollow whereas stumps are solid, and that tortillons produce slightly different textures than stumps when blending.
In practice, many artists use both. Stumps for smooth, controlled blending. Tortillons for quick work and for effects that benefit from the harder, scratchier touch. Both tools are held like a pencil and applied to the drawing surface with varying pressure and motion.
The blending stump dates to the 19th century. The Pencil Topics guide to blending stumps notes that "paper blending stumps have a rich history that dates back to the 19th century. Initially, these tools were crafted by the artists themselves, who rolled paper into cylinders with two pointed ends to help them achieve smoother blending."
Before the manufactured stump, artists used fingers, cloth, leather chamois, and rolled paper of their own making to blend dry drawing media. The Metropolitan Museum of Art's guide to chalk describes stumping as a technique in which "artists use coils of paper (known as stumps), pieces of leather, or a finger to spread the chalk. This process produces diffuse, light areas in a drawing." The technique predates the manufactured tool, but the commercial availability of stumps in the 19th century standardized the practice.
As the popularity of blending stumps grew, the transition from homemade to commercially produced versions marked a significant evolution in their availability and quality. Modern blending stumps are made from compressed paper and are available in multiple sizes, from thin stumps with a tip diameter of 3/16 inch to thick stumps with a tip diameter of 5/16 inch or more. Most stumps are about 5 to 6 inches long, which allows for a comfortable pencil-like grip.
Hold the stump like a pencil. To blend, press the tip against the area you want to soften and move it back and forth or in small circles. The motion drags drawing material from darker areas into lighter areas, creating a gradient. For broader blending, use the side of the stump. For fine work, use the very tip.
The stump picks up drawing material as it works. After a few strokes, the tip will be coated with charcoal, graphite, or pastel. This is not a problem. It is how the tool functions. A dirty stump can be used to apply a light layer of the same material to another area of the drawing, effectively transferring tone. Some artists deliberately use a loaded stump to build up subtle gray tones in areas where direct application would be too heavy.
Different effects can be achieved with different motions. Twisting the tip into a spot produces a soft, circular blend. Dragging the tip along a line softens the line without eliminating it. Pressing the side of the stump against a tonal area and sweeping it outward creates a gradient that fades to nothing. Stippling with the tip, pressing and twisting to create texture, can simulate surfaces like fur or wood grain.
The Late Night Portrait guide to tortillons describes four main techniques: blending (smooth transitions), smudging (softer, more diffuse effects using the side), layering (building tone over existing work), and texturing (using the tip to create surface effects like fur or wood).
Stumps and tortillons accumulate drawing material as they are used. A dirty stump can muddy a drawing if the accumulated material transfers to areas where it is not wanted. Cleaning is simple. For stumps, use a kneaded eraser to lift excess material from the surface, then reshape the tip with sandpaper or an emery board. For tortillons, the used outer layer of paper can be removed by scraping or rubbing on an abrasive surface. Some artists whittle off the tip if it becomes dull or mashed in.
The Wikipedia article on tortillons notes that "cleaning of tortillons and stumps usually involves removing the used outer layer of paper by scraping or rubbing it on an abrasive surface, such as sandpaper, carpet, rubber erasers, or an emery board." A sandpaper block, sold in art supply stores for sharpening pencils and stumps, is the most common cleaning tool.
Tortillons wear out and are typically thrown away when they become too saturated or the tip is too blunt to reshape. Stumps last much longer because they are solid and can be repeatedly cleaned and resharpened. The Improve Drawing guide notes that "blending stumps can last very long" while tortillons "wear out quickly and have to be thrown out."
Stumps are ideal for creating smooth, gradual tonal transitions in dry media. They are particularly useful in realist drawing, where the goal is to simulate the continuous gradients of light and shadow on three-dimensional forms. Portrait artists use stumps to blend skin tones, creating the soft transitions between highlight, mid-tone, and shadow that make a face look three-dimensional.
However, stumps can be overused. The LiveAbout guide warns that "blending stumps tend to be used a bit too often in realist drawing. The tortillon's paper fibers drag graphite across and into the surface of the paper. This creates a fine but even layer of graphite with no white paper left to reflect light. This can make the surface very dull." Over-blended drawings can look lifeless, with a mechanical smoothness that replaces the energy of direct mark-making. The best artists use stumps selectively, blending some areas while leaving others with visible, unblended strokes.
Stumps are not suitable for all media. They work best with dry, powdery materials like charcoal, graphite, pastel, and Conte crayon. They do not work with pen and ink, which is liquid and permanent, or with wet media like watercolor or oil paint. For wet blending, brushes are the appropriate tool.
Several alternatives to the stump exist for blending dry media. A finger is the oldest and most common blending tool, but it lacks precision and can transfer skin oils to the paper. A chamois cloth, a soft piece of leather, is used for broader blending and is particularly popular with charcoal artists. A kneaded eraser can be shaped into a point and used to lift material, creating highlights rather than blending. Cotton swabs and makeup applicators can be used for small-area blending, though their absorbency varies. Some artists wrap a piece of cloth or paper around a stick or knitting needle to create a custom blending tool with a specific diameter and firmness.

The stump is a small, inexpensive tool that has an outsized effect on the quality of a drawing. It is the difference between a drawing where every mark is visible and a drawing where tones flow into each other with the continuity of observed light. But like any tool, it has a specific purpose, and using it beyond that purpose produces worse results, not better. The best drawings combine blended and unblended areas, using the stump where smoothness serves the subject and leaving visible marks where energy and directness are needed.
