For example, try drawing a ball and sketch it as though the light is hitting it from one side so the opposite side is darker. Then use the stump to blend the values so the ball looks smooth and even.
For example, if you’re drawing an eye, smudge the iris so it doesn’t appear sharp or lined.
For example, if you’re drawing someone smiling with their mouth open, you might use the blending stump to create an even layer of darkness inside the mouth. Then use the stump to add darker layers near the corners of the mouth.
For example, if you’d like to draw a wispy cloud or a shadow, use the blending stump as though it were your charcoal or pencil. Rub as firmly as you like to get a slightly darker image.
If you still see bits of white, you might need to add more charcoal or graphite before spreading it again with the blending stump.
The excess graphite or charcoal will transfer to the scrap paper instead of your drawing.
The coarse sandpaper will cause the blending stump to fray as you clean it. For less fraying, use finer sandpaper. Keep in mind that you won’t be able to clean the blending stump as easily with the smoother sandpaper.
If you prefer, use a craft blade to slice off the fraying ends. Always use caution when using a craft blade and hold the blending stump steady so you don’t cut yourself.
For example, use 1 blending stump for dark values. Since you won’t be concerned about smudging lighter areas with it, you also don’t have to worry about keeping it clean. Then use a different stump for your light values.
Always cut away from you so you don’t accidentally cut yourself.
