DONE BY HAND
I saw a design by a fellow nail blogger, and wanted to try a version myself. (:
I'm not sure if she used a stencil or anything more complicated than I did, but if you'd like to know how I did attempt them: I painted the base color on all nails, painted in the lighter blue shapes with a thin brush, and dipped the brush in silver to outline them. All it takes is a steady hand to acheive detail!
