Jerome A. Barhydt, Crayon Portraiture
“ Be careful not to get too much crayon on the paper, that is, you must not "force up" or be compelled to make the shadows too dark by the use of the crayon; they should be made as dark as necessary with the stump before finishing. Should you find in finishing that they are not dark enough, use the stump to make them darker, as the pencil is only intended to give the stipple effect, and should be used in a very light and delicate way. Continue the process of finishing according to the directions hereafter given for bromide enlargements. ”
