i have been waiting too long to try this out.
1. paint a base coat with normal nail polish (i used shocking pink by china glaze).
3. pain a thin coat of crackle nail polish over (i used cracked concrete by china glaze).
4. watch in awe as the crackle stuff really "cracks"!
5. let that dry completely.
6. paint a clear top coat over for protection.
7. show all your friends!
