I used Essie Fear and Desire as my base colour and then freehanded on the colour blocks using a nail art brush with Sally Hansen Grass Slipper and Models Own Pukka Purple. If you’re not very confident with a brush, you could also use scotch tape to section off the squares and paint in the colour before peeling the tape away.
For the stitching detail, I used Black Acrylic Paint and a nail art brush. I started by outlining the blocks of colour and then adding the little stitches.
It’s all topped off with a coat of Color Club Top Coat.
