Make up sponges aren’t just for your face. They can be one of the best and easiest tools to use for nail art, specifically color fading. You can pick them up from your local discount store in big bags and each one can be used for multiple manicures.
I get my makeup sponges from a local chain called Harmon. They work great and if you ever sponge painted as a child, you can definitely implement them into your nail art! Simply load the color(s) onto the sponge and then lightly press onto your nails where you would like the color to go. Make sure you have painted your nails with a base color that is somewhat dry first.
