First, get several different glitter polishes. Glitter polish is your FRIEND!!! Have a stale mani? Just paint right over it with a glitter polish. The magic of glitter polish is, even if you have a little chip here or there, the glitter will almost conceal it!
You will see that I also had an entire nail chip off. I just made that an accent nail and my mani was fresh, new and looked wonderful! Does it look as good as a 100% fresh mani? Not really, but I did not have time for one, so this was a simple fix when I was in a jam (and don't we always need those as moms?).
