Sharpen your white and black color stick/crayon pencils and practice on gray charcoal paper with white strokes (in evenly repeated lines) to make light tones, and with black strokes to make dark tones. (Keep the lines distinct. Do not fill in areas solidly.)
- Paste a piece of plain gray charcoal paper in the middle value step of
the chart.
- Using crosshatched white color stick/crayon strokes, see if you can make three light
steps above the middle gray.
- Using crosshatched black color stick/crayon strokes, see if you can make three dark
steps below the gray.
- Cut out, and paste on the value scale. (Charcoal paper is slightly ribbed paper.)
