I know I'm a little late on the crackle phase, but this was the first chance I got to experiment with it! All crackles used are from the new China Glaze Crackle Glaze collection. Since I only have five fingers obviously, I opted to wait another time to test out Fault Line, the purple crackle. I applied the polish in various manners so that patterns differed. At first it's a little hard to get the concept of thin, put opaque coats, but it's really simple to get the hang of. I noticed that when applied Cracked Concrete it kind of broke apart the base coat underneath so that my nail was slightly visible.
