This is the first nail art challenge I've ever participated in!
Dots are harder than they look. I don't have a real dotting tool so I used the end of a chopstick and the end of one of my dental flosser thingys for the smaller dots! (Very classy)
I used All About Blue by Lilypad Lacquer as my base color and Serenity by Illamasqua for my accent nails. Then for the dots, I used Blueberry and Zipper by Colors by Llarowe on the holo nails, and on the accent nails I used All About Blue and Blueberry.
Serenity is not an easy base color to use. I redid this mani several times trying to get it to look right- I had problems with the dry time and with it looking smooth or not ridging/bunching up by the tips. I also ended up using Zipper by Colors by Llarowe for better contrast on my other nails. But I think if I do this again, I would try it with all my nails being a solid, rather than a holo, backgroun color.
I still had fun, though, and I think that Blueberry and Zipper dotted together look a little bit like peacock feathers.
