Can anyone suggest a good marker to draw on a stained canvas. I use a yellow pencil as recommended by Mark but it is too slippy and does not make a good definite contrast. It is often too faint to be helpful. I don’t want anything too complicated. i.e. charcoal and fixer etc. Just something to make a fine dark line which is easy to make out and can be painted over without problems. A solution would really help the accuracy and position placement of paint.
