Henna designs are drawn free hand. There is no rule on how or what designs to be 
drawn. Generally, mehndi designs are based on the practices followed on the 
occasions for which it is being applied and represent specific objects, dresses, 
floral designs, leaves, and birds (or animals) associated with the occassion. 
 
Stain color from natural Henna is always maroon or dark brown. Variation in 
pattern is achieved by thickness of the paste applied. Sometimes second layer of 
henna is applied next day over the first application to get darker color in some 
part of designs.
