I am in love with this design! It's actually one of my best friends that did this on her nails and when I saw it I thought it was really cute and wanted to be sure to share it!
For the black and white waves on her ring finger she cut pieces of tape and after letting the bottom layer of paint dry she placed the tape on her nail and painted over her nail with the second color. Then she gently peeled back the tape, and tah dah! The result was a perfect manicure! :D
(Thanks for letting me share this Madeline! Love ya! <3)
