No, I am not recommending neon nails for your wedding, but the idea of being able to do color gradations on your nails with gel polish is intriguing. Imagine using pale blue, fading to grey and then pale pink. very pretty and unique.
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.
