The tradition of henna tattoo design goes back thousands of years and has been passed down from generation to generation in the Middle Eastern culture. The process of creating a henna tattoo design is pretty simple. First the dried leaves of the henna plant are ground into a powder. The powder is then combined with a liquid like eucalyptus or clove oil to form a paste. The paste is then applied to the skin through a cone or applicator bottle. For those that are starting out and are not as confident, there are useful stencils. When the design or pattern is freshly applied, it will be an orange brown color. It needs to dry for a long time and eventually flake off. It's recommended 8 or more hours to dry. The longer it is allowed to dry, the darker the stain will be. After the paste has been removed and the tattoo has had time to set, normally within 24 hours, it will turn a reddish brown color.
