Acid Wash =) Paint your nails with a blue color. Apply coat of blue. Apply a white color on top. Dip a Q-tip in nail polish remover & gently swipe away the white. Be careful not to get to your bare nail.
using any polish of your choice, pour onto a flat surface, take one of those spongy eyeshadow applicators and dip into the polish, dab the polish on your nail concentrating at the tip and moving slightly upward. put a topcoat over the entire nail.
