I recently met with Roxanne Valinoti, an educator for CND, a professional nail product line, who showed me a cool trick for sponge-painted nails. This is definitely worth trying the next time the urge for DIY nail art strikes. (Or does that only happen to me?)
You'll need a natural sea sponge from a craft store and five different polishes: a clear base, a warm gold base, a midnight blue, a purple, and an iridescent topcoat. Sounds complicated, I know, but Valinoti did the whole thing in 15 minutes. Here's how to proceed:
1. Get your sponge ready by ripping off a few half-inch-long pieces. These will be easiest to hold with a pair of tweezers.
2. After applying a clear base coat, paint on the warm gold. It'll sparkle slightly through the layers but won't interfere with the darker topcoats.
3. Pour a small amount of a darker polish — which one is up to you — onto a cotton pad, then dip the sponge into the polish. Remove excess polish by dabbing the sponge onto a clean cotton pad, and then lightly press the sponge over each nail. Do the same with the other dark color. You can do several layers of each, but make sure you allow them to dry before adding another one.
4. Once the polish is dry, paint on a clear topcoat. For a futuristic effect, use an iridescent one.
