Last summer I attempted watermarbling and it was a huge fail. I tried it again about a week ago and, in my opinion, it was a success. I can't wait to try this out with different colours soon.
I forgot to take pictures until after the second full day of wear so please excuse the chipped polish on my pinky finger.
I started with a base coat of OPI No Room For The Blues and then did my watermarbling with that polish and OPI Sunbody Loves Me (pictured above) and then a coat of Seche Vite.
I find that, as with most things, practice makes perfect - I'm very much looking forward to trying this again when I have some spare time. (This took me just under an hour to do ... I had a lot of clean up to do, I forgot to use tape, gah.)
Have you tried watermarbling? Fail or success?
