The single-nail style of gradient manicure has been making the rounds on nail blogs recently—thanks in part to its simple application method (I swear!) and its endless colour possibilities. It’s also a favourite of L.A.-based nail artist Madeline Poole, whose cheery sunset-ish designs will convince anyone to make this her next manicure. And when it comes to translating spring’s underwater trend into nail art, what could be better than a deep blue to foamy white gradient? Peter Pilotto’s aquatic print—as well as the illustration that accompanied it in our March issue—served as the perfect Nail Corner inspiration. Time to break out a makeup sponge and find out how to do this manicure!
