Not sure if this is how the 'experts' do it but this is my attempt
You will need:
Two contrasting colour polishes
Top / base coat
Paint your nails your chosen colour, I chose Barry M - Racing Green
Once that is dry stick on the nail guides, the reverse of a french manicure
Paint on the contrasting colour, I used Models Own - Gun Grey
Once its dried peel off the guides and apply a top coat
And that is that all done! I think this would have been better in different colours, ones more contrasting.
What do you think?
