it is very simple to do nail art..
other than nail polish and clear polish (top coat) we need nail art kit (gem nail art kit) and nail polish striper brush.
apply light color nail polish as a base.
use striper brush and apply green nail polish as shown. (draw inclined line. and then make design as if you are drawing palm tree leaves)
then take different shade of green color and put a big dot on nail as shown ( at the center of palm tree leaves like structure)
once it is slightly dried, put a yellow color dot on green one.
we dont need dotting tool, coz here we need pretty big dots, which can be done by nail polish brush.
while the yellow polish dot is wet, put blue colored gem on it.
let it dry
then secure it with clear top coat.
