Hello! This is a watermarble I did a few weeks ago.
I used a white base (can’t remember which one), with Illamasqua Gamma, Illamasqua Jo’Mina and China Glaze For Audrey for the watermarble. The lesson learned on this mani is that while a white base will give the colors more pop, if you tape too close to your nails, then the white will show through around the edges. When the base color is also one of the colors used in the watermarble, then trying to tape closer to save clean-up is not a problem. If you don’t look too close at the edges of the mani, I think this is successful.
