The best thing about an obsession with nail polish is that you barely have to wait for your manicure to dry before there’s a new trend to try. The second best thing is, of course, just how many other people are creating incredible nail art designs and sharing them—making the online world an amazing hub (or in some cases, a rabbit hole you can get lost for hours in) of inspiration. One of the latest designs to trend online is the “outline” or “framed” manicure: a single colour mani is given retro appeal by painting a a thin line of a darker polish around the edge of the entire nail. (Like a full circle version of the slim silhouette technique!) However, given that the dexterity required for such a design is quite advanced, I created a modified version that skips the need for a skinny brush. One makeup sponge and three shades of polish are all you need for this one—and best of all, you can do it in under an hour.
