Look for a subject that has a predominance of black and good smooth gradations of light. Sketch out the outlines on newsprint that is the same size as your board.
Transfer the image to the board using carbon paper (or Saral Transfer paper) and you will be able to barely see the lines.
Practice the scratchboard techniques of cross-hatch drawing. Start with a set of lines short and all the same length and spacing apart. Do not press hard, very light touch. Next, cross them with slightly longer lines and the first set looks whiter. Repeat with a third set going in another direction even longer and now the gradation is started. Repeatedly increase the number of layers of lines in many directions to achieve a smooth change of light to dark.
You are taking black off of a white board so start at the lightest areas and work to the black. This means that the drawing will not look like much for the first part of the process but soon it will start to look good.
If you need to put black back on, you can use drawing ink pens, but you can’t scratch it out again. Spray with Crystal Clear Acrylic Spray Paint at the end to protect it and make it shine.
