Use the tip of the chalk (just as you would a pencil) to create thin lines and shapes.
Use the side of the chalk to shade larger areas. Press lightly for less color, and apply more pressure for darker color.
Color with chalk on the paper. Then rub it gently with a tissue, cotton ball, or paper towel.
Create subtle lines or shadows by using a cotton ball or your fingers to blur the edges of the chalk between two colors.
Create new colors and effects by starting with one color of chalk and blending other colors over the top.
To shade an area, draw many lines of chalk parallel to each other. The closer the lines are together, the darker the shading will appear.
Begin by using the hatching technique, and then add more lines perpendicular to the first set. As with hatching, the closer the lines are, the more saturated the color will appear.
Gradually increase the pressure used on the chalk to increase the saturation of color, or gradually decrease the pressure to make the color more subtle.
Soaking chalk in water before use will give it a creamier texture, more saturated color, and smoother application. Wetting the paper will have a similar effect.
Unlike oil pastels, which are oil-based, chalk pastels are made primarily of chalk. There are a variety of chalk pastel shapes and sizes, and they also range from hard to soft.
Sidewalk chalk is usually longer and thicker and is often made up of rougher material which may scratch the surface of some chalkboards. It is made to be used on concrete or pavement. Try using it both dry and wet for different color effects!
Chalkboard chalk is usually longer, thinner, and softer and may not stand up well on the rough surfaces outside. Although once made of calcium carbonate, most chalks are now made from the mineral calcium sulfate.
Create different effects with different paper textures. The rougher the paper, the more chalk will be transferred in a single stroke.
Colored paper can help make your drawings more realistic. See how easy it is to draw a round ball using just black and white chalk on gray paper?
