These are the things I used for this design :)
Paint a clear coat on each nail
Paint a plain black coat on each nail
Use your dotter tool to create groups of 5 dots around your nail. Also, do some singular dots at the edges of your nail.
Repeat this step for each nail.
Use a smaller dotting tool to create little lines/dots on the inside of the white dots as shown.
Repeat for each nail.
Place a small blob of yellow in the centre if each cluster of dots.
Use a cotton bud to clean up around your nails.
Repeat on the other hand.
Now you have some cool daisy nails to show off to all your friends :)
