Place tape at the very edge of your nail, running along the cuticle. It should be a little larger than your average French-tip
Take your pink/red and paint the open nail
Pull off the tape right away!
Put your stripping tape along the edge of the pink, then take your light green and paint the open space
Remove tape immediately!
Add white very carefully along the empty space between pink and green. It doesn't matter if it's messy, you can fix that.
Add color to either side to make the line more natural
Add tiny black teardrops to the pink
And dark green lines from the white up on the light green
Hey, I'm no pro. I'm sure you're lots better. good luck!
