I've seen this a couple of times on Instagram now & wondered how the hell they did it, so I searched it on google & it came up with like a million tutorials & it's surprisingly easy, although very messy !
I won't do a tutorial on here because there is some amazing ones on YouTube if you type in water marble nail art, but you basically need a cup of water - room temperature, a couple of nail polishes, the higher pigment the better, some tape & some sort of stick (I just used a cocktail umbrella stick ). Then you dip your first colour of polish into the water & it should spread out then repeat with your second colour & again with the first about ten times, with your stick bring the outside of the polish into the centre & try to be as quick as you can as it drys really quick on the water, now dip your finger in tip first (remember to tape around the edges of the nail ) pull any polish left on the water away with your stick then remove your finger :) it does take a while as you have to repeat this for every finger but the amount of compliments I've had on these make it well worth it ! Does anyone know of another ways of doing the marble look ? Or any one else have any pictures of your own ? I'd love to see :)
