I used Blue Marlin and Strawberry Sundae in this watermarble mani. As you can see, I need heaps more practice. But luckily I won a set of the top 15 bestseller bottles of ulta3 polish to play with from Sonailicious and have plenty of good quality cremes to play with.
My patterns are a bit off. Other people loved it, but I always end up feeling a bit ambivilent about watermarbles. I think it's because it's a bit psycheldelic and I'm just not into the 60s hippy look.
After a couple of days I added the Glisten and Glow holo top coat. Unfortunately it dulled the colour a bit, so I'm not sure if I should have done that.
