Take a dark polish
I used dark purple for this one.
After the polish dries, you take a light color. I used green.
Now you make a line, begin at the top of the nail left and make a line (really) a little bit to the bottem of the nail right. left you start a big line and when you finish right it have to be a smal line.
Now you pick another light color, as you see I used orange.
with this one you follow at the bottem the green line.
at the top of the nail you put a really small stripe. it don't have to touch the green line.
for the last stap you pick again another light color. I used yellow.
at the bottem of the nail je make some dots. it have to look like a flower or a sun. you can use 3 dots or 4.
I used 3 but the last one you can't heardly see.
As finishing you can take a clear nail varnish, and you done.
