To create the design I used a thin paintbrush and a dotting tool. Here's what they look like. You can see below that the paintbrush used to be a little thicker but I've cut some of the bristles to make it a little thinner.
I started by painting my nails blue and letting that dry.
Next using the thin paintbrush and some white polish I painted little lines radiating from the centre of each nail. These lines do not have to be the same length or in the same place for each nail.
I then took the dotting tool and dipped it in a yellow polish before creating a dot in the centre of each daisy. The polish I used was slightly translucent, so I ended up adding two layers of dots.
I then added a topcoat, to smooth out the design and try to make it last a little longer.
