Print off the stencil and choose a size suitable for your arm.
Cut out the design.
Use an Exacto knife to cut out the eye sockets (this will give you a guideline for where to place the skull) as well as the 'holes' in the snake where it makes the figure 8.
Place the template on your friend's arm and trace around it using a pen or eyeliner.
Once the outline is complete, remove the stencil and fill in the details using the stencil as a reference.
Start tracing the design using henna.
Try to apply the henna at a vertical 90 degree angle, this will help you be more precise and prevent your hand from smudging the work you have done before.
Let the henna dry. The longer you leave it on, the darker it's supposed to be.
Once you've left it on long enough, scratch and rub the henna off. Wash off the pen or eyeliner with soap and water.
