Decide where you want your henna tattoo. You can get it either on your palm or on the outside of your hand, depending on your personal preference. The henna will show up darker on the inside of the palm, but more people will see the outside of the hand. You could choose to get both done and look for a design that covers both areas.
Choose smaller elements to create a larger design. Typically, henna designs are made up of many small components put together in a pleasing manner. It may be a series of dots, flowers, vines and lines, but when it comes together it creates something really beautiful.
