Watercolor Technique For Trying Ideas With Tracing Paper
Flipping and rubbing
To prepare your new design elements for transfer you need to turn your tracing paper into transfer paper.
Any soft lead graphite instrument will do. I use graphite sticks because you can cover large areas quickly by using the side of the stick.
On a flat, smooth surface such as the back of a drawing pad or scrap foam board, flip your tracing paper over and rub graphite over the areas where your lines are.
Remember, you are coating the BACK of the drawing with a fairly dense coat of graphite.
