I HATE water marble! I tried it some years ago, the first time i saw it, and i wasn't able to do it. I tried hot, cold, room temperature water...and nothing. I tried different polishes and what i got was a mess, everytime! This time I had to try it again! It's like a curse on me. And also this time i used different polishes and water many and many times...and when i used these green colors and something acceptable came up on my nails i decided that it was ok! XD I don't know how so many people can do it so perfectly...u.u I like the marbled effect, it's so unusual...but after this final attempt i think that it's over with water marble XD ahah
