1 Make a fine paste line near your top knuckle, and let that dry. 2  Apply thick henna paste up to that line. 3  As the paste dries and bare spots open up, fill those in with more henna. 4  Leave that on for one hour or more. 5  For darker color and more even stain, scrape the paste back and reapply henna a second time.he stain may be dark as the picture at the top of the page or a deep red color, depending on your skin and the henna you use. Other techniques from history: 1  Mix the henna very thick, like pie dough, and press the thick paste onto your fingertips and fingernails.
Henna is applied to clean, dry skin. This can take anywhere from a few minutes for a simple design to 4 or 5+ hours for a heavy bridal mehndi. Once dry, it will be sealed with a sugar solution, or taped with medical tape (for body pieces). Let henna paste set for 8 hours, though overnight is traditional and guarantees the best color.
