Copy the design from the paper onto the desired area with the laundry pen. This will be a guideline for applying the henna. To avoid drawing freehand, trace the design onto tracing paper with the laundry pen, then apply roll-on deodorant to the skin where the tattoo will be. Lay the tracing paper on the area, marker-side down, and press gently. Wait about two minutes before gently peeling the paper away. This will transfer the design from paper to skin.
