I used NYC Cashemere Creme as my base coat and then attempted to do a rainbow like fan on the accent nail. The accent nail didn't turn out as I had planned, but it's not terrible :-P I added a blue rhinestone for one more special effect!
Make sure you go check out this polish in my etsy store Llama Lacquers. While you are there take a look at all the other polishes in the collection as well. Thanks for checking me out!! I love all your comments :-)
