Yesterday I did my nails water marbling. Before I did the water marbling I put 1 coat of Sinful colors snow me white. Once that was dry I started the water marbling. I like to put tape around my finger so its not such a mess to clean up. I used filtered room temperature water I guess thats works best im not sure because I havent used any other water. When you do this you have to work very fast otherwise the nail polish will dry and it wont work. So the colors I used were NYC fuchsia shock creme Essence no more drama Piggy polish blue me a kiss and Savvy FC knightly armour. I used the savvy nail polish in the marbling and when it drier over my whole nail I put 1 coat. Hope this helped.
