I saw a few days ago an amazing tutorial done by Cute Polish on youtube. I found it so cool and was so impressed with the result I had to try it as soon as possible. You can find this tuotial HERE.
And thanks to Pam from Girly Bits for sharing this video on her FB page ;D
This tutorial from Cute Polish will explain you how to create a spotted look. You'll get a similar restult as with OPI Black Spotted (HERE & HERE)!
Of course the size of the sprayer you use will influence the size of the spots you obtain. Moreover, if you spray close from the water you will get larger spots. That's why you will have to get some practice before getting the design you want.
Here is a tutorial I did. Once again, I want to give credits to Cute Polish for the idea of this design :D
