Take all the things you need!
If you want, you can add a base coat.
Paint your nails in one colour, this colour has to be lighter than the colours you want to make your flowers with.
Make with the next colour a round of 5 dots.
Go with a toothpick from the middle from a dot to the middle of the circle of dots.
Repeat step 3 and 4 on every finger, you can make as much flowers as you want.
Put, with another toothpick, a dot in the middle of a flower.
Repeat this with every flower.
Tadada! You're done :)
