Now the OPI one is unique BUT it always reminds me of dirty water drying slowly. You know when you spill something and it starts drying in random patches. You know!
With this technique I feel like the base colour and the colour you choose to use on top of it look better together. They look like 1. Does that make sense? Anyways there are not perfect(See right hand) but I will for sure try these out again. They are much easier then water marbling! And you can do them in any colour!
I used OPI My Boyfriend Scales Walls for the base and Black Onyx for the top. I did the accent nails with Milani Dude Blue and BK Sweet Candy Fast Dry Nail Art Polish in #19* on my left hand and China Glaze Urban-Night and Essie Pretty Edgy on my right.
