D.I.Y Nail Sponge.

You Will Need:

-An old pair of tweezers.
-A sponge.
-Two bobby pins.
-A pair of scissors.

The Steps:

-Cut a small triangle of sponge from an old makeup sponge of cleaning sponge.
-Place the triangle of sponge between the tweezers so that one edge points outwards and the other two are held by the tweezers.
-Take a bobby pin and use it to hold the tweezers closed (I used two for added strength.)

TIP: With this nail sponge you can also get neater results on your weaker hand by using the bobby pins to keep the sponge steady.
