I love painting my ring finger different from the rest of my nails using either glitter nail polish or nail strips. I found Sally Hansen salon effect strips which I love, but one tip is when you open the pack you have to use them all. If you try to use the rest of the pack later on you will find that they are no longer sticky. One advantage to the nail strips is that they can last up to two weeks.
I love the end result with the pink next to the multi-color glitter. Another color combination I love is emerald green and gold.
What color combinations have you tried?
