I decided to go with water marble decals which seem to be popular lately. The idea is that you do your regular water marble.
Instead of dunking your finger in, you let it dry for a long time (I did about an hour I think) and gently lift it out, letting it dry on paper towel.
Then you can cut the decal and apply it to a semi sticky base on your nail.
I see tons of advantages to this: less waste (I used one go for 4 nails), less mess, time saver (I marbled more nap time and finished my nails during nap), and more accurate (you can redo the marble over and over again without redoing your whole nail plus you can cut the exact part you want to use instead of hoping you're dunking right!).
Onto the mani!
I used China Glaze Kalahari Kiss as the base for my thumb, ring, and pinkie. I also used it along with Zoya Pepper and O.P.I. Chop-sticking to My Story for the water marble decal.
The brown glitter is Hits Glitter Forte 389 Brown.
