A few weeks ago I came across an article through Makeup Talk discussing how to turn pigments like a M•A•C eyeshadow into a nail polish. I've posted about it several times on my Facebook but don't recall sharing this with my blog readers.

So have you ever hated an eyeshadow you bought and couldn't return it for whatever reason? Well this maybe for you then!

What you'll need:

1. silicone baking tins (you can get these at a craft store like Hobby Lobby or Michaels and use a 40% to 50% off coupon to get it for cheap).
2. mixing spoon of some type or chop stick.
3. clean nail polish
4. pigment/shadow of your choice

First start by adding a small amount of pigment/shadow into the baking tin then slowly add the clear polish and mix well. Work in small batches. She mentions that the polish will be thicker than normal polish so if you want it thinner then add more clear polish.

She also mentions in her article you can also change the color of an existing polish the same way. Again she recommends to work in small batches.
