One thing that any nail polish fan knows is that sometimes you get sick of a color halfway through the bottle and never use it again. What can you do with all that leftover polish? There are tons of craft ideas out there, but this one helps you use up old polish AND give your jewelry a totally new look. Try it out on a piece of jewelry you can stand to lose if you mess up (or keep a bottle of nail polish remover on hand!). Like with most crafts, this is also a great gift idea!
