I used an ELF Studio small precision brush to apply the spots randomly.
Then I used a small glass dish (One that I use for nail polish) to pour some Sinful Colors Secret Admirer in to See my review for Secret Admirer here. I picked up some polish with a toothpick and traced C shapes around the spots. Needless to say, my right hand was not as wonderfully spotted as my left hand, but it looked decent.
I alternated every nail in color, so in color schemes, the pattern was, starting from L to R, gray, green, pink, purple, gray, green, pink, purple, gray green.
I think the pink nail looks the best! My boyfriend said he liked the green one best. I have more and better pictures, but I need to charge my camera battery. Enjoy!
