I thought this was such a cute look when I saw it, so I recreated it for you guys :) If you want it to be more colorful you can use 4 different colors for the puzzle pieces, as long as the color are very contrasting.
Sorry for the quality of the pictures, it's not as nice as I wanted it to be.
The white I used is OPI Funny Bunny and the Black is Golden Rose Striper Polish in no. 106
I came across the look on Google and thought is was just too cute not to recreate. Hope you like it :)
Have a great day.
